GENERAL DESCRIPTION
The ADL5357 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and LO balancing circuitry
to allow for single-ended operation. The ADL5357 incorporates
an RF balun, allowing for optimal performance over a 500 MHz to
1700 MHz RF input frequency range using high-side LO injection
www.DafotarSRhFeefrt4eqUu.ceonmcies from 500 MHz to 1200 MHz and low-side
injection for frequencies from 900 MHz to 1700 MHz. The
balanced passive mixer arrangement provides good LO-to-RF
leakage, typically better than −46 dBm, and excellent inter-
modulation 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 8.6 dB and can be used
with a wide range of output impedances.

The ADL5357 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
ADL5357 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 ADL5357 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.
