Description
The AWB7238 is a fully matched, Multi-Chip-Module (MCM) designed for picocell, femtocell, and customer premises equipment (CPE) applications. Consisting of two parallel-path high-linearity, high-efficiency power amplifiers, the device meets the extremely demanding needs of small cell infrastructure architectures. Designed for LTE, WCDMA, and HSDPA air interfaces operating in the 791 to 821 MHz bands, the AWB7238 delivers up to +27 dBm of LTE (E-TM1.1) power through an external 90° hybrid coupler with an ACPR of -47 dBc. The device operates from a convenient +4.5 V supply and provides 30 dB of gain.
The device is manufactured using an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. The self-contained 7 x 7 x 1.3 mm surface-mount package incorporates RF matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.
A block diagram of the AWB7238 is shown in Figure 1. The device package and pinout are shown in Figure 2. Signal pin assignments and functional pin descriptions are described in Table 1.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at
or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. 2 At output of external 90 hybrid coupler. 3 JEDEC JS-001-2010. 4 JEDEC JESD22-C101D.
ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times.
