GENERAL DESCRIPTION

The ADL5353 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and local oscillator (LO)
balancing circuitry to allow for single-ended operation. The
ADL5353 incorporates an RF balun to provide optimal perfor­mance over a 2200 MHz to 2700 MHz input frequency range
using high-side LO. The balanced passive mixer arrangement
provides good LO-to-RF leakage, typically better than −36 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 might 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 8.8 dB and can be used with a
wide range of output impedances.

Figure 1.

The ADL5353 provides two switched LO paths that can be used
in TDD applications where it is desirable to rapidly switch 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 ADL5353 is
capable of operation at voltages down to 3.3 V with substantially
reduced current. For low voltage operation, an additional logic
pin is provided to power down (<200 µA) the circuit when desired.

The ADL5353 is fabricated using a BiCMOS high performance
IC process. The device is available in a 5 mm × 5 mm, 20-lead
LFCSP and operates over a −40°C to +85°C temperature range.
An evaluation board is also available.
