Description
Bias Adj
The XZ1004-QT is an integrated front end GaAs IC
for MoCA mid-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 a 3 dB switched attenuator and 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 power
down functionality and optional bias adjustment.
The device typically delivers 20 dBm at P1dB and
+34 dBm OIP3 across the operating temperature
range. The digital inputs control all circuit operating
modes and are compatible with Entropic’s MoCA
chipsets.
