#Linear power amplifier free#
The QFN package is lead free and halogen free, and it has a moisture sensitivity rating of MSL-2a to permit a floor-life of four weeks out of the bag. The MGA-43128 is offered in a miniature 5.0 x 5.0 x 0.85 mm surface mount, 28-lead QFN package and operates over a temperature range of -40° C to +85° C.
#Linear power amplifier series#
All devices in the series have a common package footprint to further simplify design. The 700 MHz device joins the company’s 29 dBm linear power amplifier family, following the released MGA-43228 and MGA-43328 power amplifiers that cover 2300 to 2500 MHz and 2500 MHz to 2700 MHz, respectively. The MGA-43128’s very linear output power is achieved by using an Avago proprietary 0.25 µm GaAs Enhancement-mode pHEMT process, which allows single 5-V supply operation and useable performance down to 3.3 V. An integrated bypass switch controlled attenuator provides up to 18.0 dB attenuation, and the device also has a temperature-compensated power detector on chip. RF input is fully matched while the output includes integrated pre-match circuitry for matching and application simplicity. Designed for superior signal quality while transmitting at high data rates, the MGA-43128 features low distortion and high power added efficiency (PAE) that help reduce power consumption.
