GENERAL DESCRIPTION
The ADL5369 uses a highly linear, doubly balanced passive mixer
core along with integrated radio frequency (RF) and local oscillator
(LO) balancing circuitry to allow single-ended operation. The
ADL5369 incorporates an RF balun, allowing optimal performance
over a 300 MHz to 1100 MHz RF input frequency range. The
balanced passive mixer arrangement provides good LO to RF
leakage, typically better than −25 dBm, and excellent intermod-
ulation 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 perform-
ance. The passive mixer core yields a typical power conversion loss
of 6.2 dB.

The ADL5369 provides two switched LO paths that can be
used in time division duplex (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 ADL5369 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 (<200 μA) the circuit when desired.
The ADL5369 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.
