GENERAL DESCRIPTION
The ADL5365 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and LO balancing circuitry
to allow for single-ended operation. The ADL5365 incorporates
an RF balun, allowing for optimal performance over a 1200 MHz
to 2500 MHz RF input frequency range using high-side LO
injection for RF frequencies from 1700 MHz to 2500 MHz and
www.DalotawS-shiedeet4inUje.ccotimon for frequencies from 1200 MHz to 1700 MHz.
The balanced passive mixer arrangement provides good LO-to-
RF leakage, typically better than −30 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.

The ADL5365 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
ADL5365 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 ADL5365 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.
