XZ1004-QT Front End GaAs IC 475 - 625 MHz Features  MoCA Compliant Front-End GaAs IC  Linear Power Amplifier  Integrated PA Bias Control  PA Power Down Mode  Transmit/Receive Switch  Transmit Power Detector  0/3 dB Transmit Attenuator  0/15 dB Receive Attenuator  3.3 Volt Single Bias  Integrated Digital Control Logic  Compatible with EN2512 & EN2552  Lead-free 3 mm 16-lead PQFN Package  RoHS* Compliant  50 Ω Characteristic Impedance Description 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.

A logic high input voltage enables the 15 dB receive attenuator. Digital input. A logic high voltage selects transmit mode, logic low selects receive mode. Digital input. A logic high selects calibration mode (transmit amplifier output is diverted into the power detector). This pin overrides the TX_RX control input. Transmit RF input (50 Ω). Digital input. A logic low input voltage enables the 3 dB transmit attenuator. Digital input. A logic low input voltage reduces the ID1 current. Bias supply. Bias adjustment of transmit amplifier using pull-up/down resistor (normally connected to VDD). Amplifier bias supply. External inductor connected to this pin sets the transmit return loss and linearity levels. RF input in the receive mode and RF output in the transmit mode (50 Ω). External RC network connected to this pin sets the power detector sensitivity. Detector bias supply. Power detector output voltage. Used during calibration mode to measure output power. Receive RF output (50 Ω). External RC network connected to this pin sets the receive attenuator gain step. 2 M/A-COM Technology Solutions Inc.
