Description
The XZ1003-QT is an integrated front end GaAs IC
for MoCA High-band RF applications which is fully
compatible with Entropic Communications chipset. It
is housed in an industry standard 3 mm PQFN
package and operates from a single 3.3 V bias. The
chip includes a power amplifier, transmit/receive
switch, power detector, switched attenuators, bias
circuits and digital control circuitry. The transmit path
includes two 3 dB switched attenuators and a power
detector for gain adjustment and linearity
optimization. A switched attenuator in the receiver
provides a 15 dB gain step. The integrated bias
circuit stabilizes transmit amplifier performance over
temperature and process variation with optional bias
adjustment. The device typically delivers 20 dBm at
P1dB and +32 dBm OIP3 across the operating
temperature range. The digital inputs control all
circuit operating modes and are compatible with
Entropic’s MoCA chipsets.
