Heterojunction Bipolar Transistor Technology (InGaP HBT)
High Efficiency/Linearity Amplifier

The MMZ25332B is a 2--stage, high linearity InGaP HBT broadband amplifier designed for femtocell, picocell, WLAN (802.11g/n), W--CDMA, TD--SCDMA and LTE wireless broadband applications. It provides exceptional linearity for LTE and W--CDMA air interfaces with an ACPR of –50 dBc at an output power of up to 22 dBm, covering frequencies from 1500 to 2800 MHz. It operates from a supply voltage of 3 to 5 V. The amplifier is fully input matched, requires minimal external matching on the output and is housed in a cost--effective, surface mount QFN 3 x 3 package. The device offers state--of--the--art reliability, ruggedness, temperature stability and ESD performance.
