A new gallium arsenide MMIC three stage buffer amplifier features ultrawide bandwidth and high dynamic range.
MMIC mixer is optimised as downconvertor
A new gallium arsenide monolithic microwave integrated circuit fundamental balanced mixer is optimised for use as a downconvertor.
This family of devices achieves 11dB of gain and less than 2.5% EVM at 30dBm output power, with an OFDM input signal and a peak to average ratio (PAR) of 9dB.
The devices operate off a single supply voltage up to 12V and include internal active bias circuitry.
The CHV family includes the added feature of analogue adjustment of bias current to address a variety of applications.
These linear power amplifiers, identified as CHV2707, CHV2710 and CHV2711, operate at 700MHz, 2.5GHz and 3.5GHz, respectively.
Evaluation boards are available to help engineers test the products and apply them to their designs.
"The complex data formats associated with WiMAX signals make it essential that these amplifiers provide exceptional linearity at the highest data transmission format, and that they are adjustable when lower data formats are used".
"By delivering 1W average power under maximum data transmission, including on-chip bias circuitry, and providing a separate bias current adjustment in a standard QFN plastic package, we provide our broadband customers with unparalleled performance, flexibility and cost savings", stated Damian McCann, CTO of Mimix Broadband.
