GENERAL DESCRIPTION
The ADL5355 provides two switched LO paths that can be
The ADL5355 uses a highly linear, doubly balanced passive
mixer core along with integrated RF and LO balancing circuitry
to allow for single-ended operation. The ADL5355 incorporates
an RF balun, allowing for optimal performance over a 1200 MHz
to 2500 MHz RF input frequency range using low-side LO
injection for RF frequencies from 1700 MHz to 2500 MHz and
high-side LO injection for RF frequencies from 1200 MHz to
1700 MHz. The balanced passive mixer arrangement provides
good LO-to-RF leakage, typically better than −39 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
gain of 8.4 dB and can be used with a wide range of output
impedances.
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
ADL5355 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 ADL5355 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.
