GENERAL DESCRIPTION
The ADL5363 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
ADL5363 incorporates an RF balun to provide optimal
performance over a 2300 MHz to 2900 MHz input frequency
range. The balanced passive mixer arrangement provides good
LO-to-RF leakage, typically better than −30 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.

The ADL5363 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 ADL5363 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 ADL5363 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.
