GENERAL DESCRIPTION
The ADL5367 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and LO balancing circuitry
to allow for single-ended operation. The ADL5367 incorporates
an RF balun, allowing optimal performance over a 500 MHz to
1700 MHz RF input frequency range. Performance is optimized for
RF frequencies from 500 MHz to 1200 MHz using a high-side LO
and for RF frequencies from 900 MHz to 1700 MHz using a
low-side LO. The balanced passive mixer arrangement provides
good LO to RF leakage, typically better than −35 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 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
loss of 7.7 dB and can be used with a wide range of output
impedances.

Figure 1.
The ADL5367 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
ADL5367 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 ADL5367 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.
