GENERAL DESCRIPTION

The ADL5356 uses a highly linear, doubly balanced, passive mixer core along with integrated RF and local oscillator (LO) balancing circuitry to allow single-ended operation. The ADL5356 incorporates the RF baluns, allowing for optimal performance over a 1200 MHz to 2500 MHz RF input frequency range. Performance is optimized for RF frequencies from 1700 MHz to 2500 MHz using a low-side LO and RF frequencies from 1200 MHz to 1700 MHz using a high-side LO. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −35 dBm, and excellent intermodulation performance. The balanced mixer core also provides extremely high input linearity, allowing the device to be used in demanding cellular applications where in-band blocking signals may otherwise result in the degradation of dynamic performance. A high linearity IF buffer amplifier follows the passive mixer core to yield a typical power conversion gain of 8.2 dB and can be used with a wide range of output impedances.
The ADL5356 provides two switched LO paths that can be used in TDD applications where it is desirable to ping-pong between two local oscillators. LO current can be externally set using a resistor to minimize dc current commensurate with the desired level of performance. For low voltage applications, the ADL5356 is capable of operation at voltages down to 3.3 V with substantially reduced current. Under low voltage operation, an additional logic pin is provided to power down (<300 µA) the circuit when desired.

CIRCUIT DESCRIPTION

The ADL5356 consists of two primary components: the radio frequency (RF) subsystem and the local oscillator (LO) subsystem. The combination of design, process, and packaging technology allows the functions of these subsystems to be integrated into a single die using mature packaging and interconnection technologies to provide a high performance, low cost design with excellent electrical, mechanical, and thermal properties. In addition, the need for external components is minimized, optimizing cost and size.
The RF subsystem consists of integrated, low loss RF baluns, passive MOSFET mixers, sum termination networks, and IF amplifiers. The LO subsystem consists of an SPDT-terminated FET switch and two multistage limiting LO amplifiers. The purpose of the LO subsystem is to provide a large, fixed amplitude, balanced signal to drive the mixer independent of the level of the LO input.
A block diagram of the device is shown in Figure 52.

RF SUBSYSTEM

The single-ended, 50  RF input is internally transformed to a balanced signal using a low loss (<1 dB) unbalanced-to-balanced (balun) transformer. This transformer is made possible by an extremely low loss metal stack, which provides both excellent balance and dc isolation for the RF port. Although the port can be dc connected, it is recommended that a blocking capacitor be used to avoid running excessive dc current through the part. The RF balun can easily support an RF input frequency range of 1200 MHz to 2500 MHz.
07883-001
The resulting balanced RF signal is applied to a passive mixer that commutates the RF input with the output of the LO subsystem. The passive mixer is essentially a balanced, low loss switch that adds minimum noise to the frequency translation. The only noise contribution from the mixer is due to the resistive loss of the switches, which is in the order of a few ohms.
Because the mixer is inherently broadband and bidirectional, it is necessary to properly terminate all the idler (M × N product) frequencies generated by the mixing process. Terminating the mixer avoids the generation of unwanted intermodulation products and reduces the level of unwanted signals at the input of the IF amplifier, where high peak signal levels can compromise the compression and intermodulation performance of the system. This termination is accomplished by the addition of a sum network between the IF amplifier and the mixer and in the feedback elements in the IF amplifier.
The IF amplifier is a balanced feedback design that simultaneously provides the desired gain, noise figure, and input impedance that is required to achieve the overall performance. The balanced open­collector output of the IF amplifier, with impedance modified by the feedback within the amplifier, permits the output to be connected directly to a high impedance filter, differential amplifier, or an analog-to-digital input while providing optimum second­order intermodulation suppression. The differential output impedance of the IF amplifier is approximately 200 . If operation in a 50  system is desired, the output can be transformed to 50  by using a 4:1 transformer.
The intermodulation performance of the design is generally limited by the IF amplifier. The IP3 performance can be optimized by adjusting the IF current with an external resistor.
Figure 41, Figure 43, and Figure 44 illustrate how various IF and LO bias resistors affect the performance with a 5 V supply. Additionally, dc current can be saved by increasing either or both resistors. It is permissible to reduce the dc supply voltage to as low as 3.3 V, further reducing the dissipated power of the part. (No performance enhancement is obtained by reducing the value of these resistors, and excessive dc power dissipation may result.)

LO SUBSYSTEM

The LO amplifier is designed to provide a large signal level to the mixer to obtain optimum intermodulation performance. The resulting amplifier provides extremely high performance centered on an operating frequency of 1700 MHz. The best operation is achieved with either low-side LO injection for RF signals in the 1700 MHz to 2500 MHz range or high-side injection for RF signals in the 1200 MHz to 1700 MHz range. Operation outside these ranges is permissible, and conversion gain is extremely wideband, easily spanning 1200 MHz to 2500 MHz, but intermodulation is optimal over the aforementioned ranges.
The ADL5356 has two LO inputs permitting multiple synthesizers to be rapidly switched with extremely short switching times (<40 ns) for frequency agile applications. The two inputs are applied to a high isolation SPDT switch that provides a constant input impedance, regardless of whether the port is selected, to avoid pulling the LO sources. This multiple section switch also ensures high isolation to the off input, minimizing any leakage from the unwanted LO input that may result in undesired IF responses.
The single-ended LO input is converted to a fixed amplitude differential signal using a multistage, limiting LO amplifier. This results in consistent performance over a range of LO input power. Optimum performance is achieved from −6 dBm to +10 dBm, but the circuit continues to function at considerably lower levels of LO input power.
The performance of this amplifier is critical in achieving a high intercept passive mixer without degrading the noise floor of the system. This is a critical requirement in an interferer rich environment, such as cellular infrastructure, where blocking interferers can limit mixer performance. The bandwidth of the intermodulation performance is somewhat influenced by the current in the LO amplifier chain. For dc current sensitive applications, it is permissible to reduce the current in the LO amplifier by raising the value of the external bias control resistor. For dc current critical applications, the LO chain can operate with a supply voltage as low as 3.3 V, resulting in substantial dc power savings.
In addition, when operating with supply voltages below 3.6 V, the ADL5356 has a power-down mode that permits the dc current to drop to <300 µA.
The logic inputs are designed to work with any logic family that provides a Logic 0 input level of less than 0.4 V and a Logic 1 input level that exceeds 1.4 V. All logic inputs are high impedance up to Logic 1 levels of 3.3 V. At levels exceeding 3.3 V, protection circuitry permits operation up to 5.5 V, although a small bias current is drawn.

APPLICATIONS INFORMATION

BASIC CONNECTIONS

The ADL5356 mixer is designed to downconvert radio frequencies (RF) primarily between 1200 MHz and 2500 MHz to lower intermediate frequencies (IF) between 30 MHz and 450 MHz. Figure 53 depicts the basic connections of the mixer. It is recommended to ac-couple the RF and LO input ports to prevent non-zero dc voltages from damaging the RF balun or LO input circuit. The RFIN matching network consists of a series 1.8 pF capacitor and a shunt 15 nH inductor to provide the optimized RF input return loss for the desired frequency band.

IF PORT

The mixer differential IF interface requires pull-up choke inductors to bias the open-collector outputs and to set the output match. The shunting impedance of the choke inductors used to couple dc current into the IF amplifier should be selected to provide the desired output return loss.
The real part of the output impedance is approximately 200 Ω, as seen in Figure 30, which matches many commonly used SAW filters without the need for a transformer. This results in a voltage conversion gain that is approximately 6 dB higher than the power conversion gain, as shown in Ta ble 3 . When a 50 Ω output impedance is needed, use a 4:1 impedance transformer, as shown in Figure 53.

BIAS RESISTOR SELECTION

The IF bias resistors (R1 and R4) and LO bias resistors (R2 and R5) are used to adjust the bias current of the integrated amplifiers at the IF and LO terminals. It is necessary to have a sufficient amount of current to bias both the internal IF and LO amplifiers to optimize dc current vs. optimum IIP3 performance. Figure 41, Figure 43, and Figure 44 provide the reference for the bias resistor selection when lower power consumption is considered at the expense of conversion gain and IP3 performance.

MIXER VGS CONTROL DAC

The ADL5356 features three logic control pins, VGS0 (Pin 24), VGS1 (Pin 25), and VGS2 (Pin26), that allow programmability for internal gate-to-source voltages for optimizing mixer performance over desired frequency bands. The evaluation board defaults VGS0, VGS1, and VGS2 to ground. Power conversion gain, NF, IIP3, and input P1dB can be optimized, as shown in Figure 39 and Figure 40.

Power Supply Decoupling. Nominal supply decoupling consists of a
0.01 μF capacitor to ground in parallel with 10 pF capacitors to ground positioned as close to the device as possible.
RF Main and Diversity Input Interface. Main and diversity input channels are ac-coupled through C9 and C11. Z1 to Z4 provide additional component placement for external matching/filter networks. C2, C3, C6, and C7 provide bypassing for the center taps of the main and diversity on-chip input baluns.
IF Main and Diversity Output Interface. The open collector IF output interfaces are biased through pull-up choke inductors L1, L2, L4, and L5, with R3 and R6 available for additional supply bypassing. T1 and T2 are 4:1 impedance transformers used to provide a single-ended IF output interface with C27 and C28 providing center-tap bypassing. C17, C19, C20, C29, C30, C31, C32, and C33 ensure an ac-coupled output interface. Remove R9 and R10 for balanced output operation.
LO Interface. C14 and C16 provide ac coupling for the LOI1 and LOI2 local oscillator inputs. LOSEL selects the appropriate LO input for both mixer cores. R15 provides a pull-down to ensure LOI2 is enabled when the LOSEL jumper is removed. Jumper can be removed to allow LOSEL interface to be exercised using external logic generator.
PWDN Interface. When the PWDN 2-pin shunt is inserted, the ADL5356 is powered down. When R19 is open, it pulls the PWDN logic low and enables the device. Jumper can be removed to allow PWDN interface to be excercised using an external logic generator. Grounding the PWDN pin is allowed during nominal operation but is not permitted when supply voltages exceed 3.3 V.
Bias Control. R16 and R17 form a voltage divider to provide a 3 V for logic control, bypassed to ground through C34. R7, R8, R11, R12, R13, and R14 provide resistor programmability of VGS0, VGS1, and VGS2. Typically, these nodes can be hardwired for nominal operation. Grounding these pins is allowed for nominal operation. R2 and R5 set the bias point for the internal LO buffers. R1 and R4 set the bias point for the internal IF amplifiers. L3 and L6 are external inductors used to improve isolation and common-mode rejection.
