Amp buffers wide-bandwidth applications

Gallium arsenide MMIC wideband buffer amplifier features on-chip drain bias coil and DC blocking.

The latest gallium arsenide MMIC wideband buffer amplifier from Mimix Broadband comes with an on-chip drain bias coil and DC blocking.

Using 0.30um-gate-length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, the buffer amplifier covers the 2 to 18GHz frequency bands and has a small signal gain of 9dB with a noise figure of 4.5dB across the band.

The CMM4000-BD also achieves +19dBm P1dB compression point and is well suited for fibre optic, microwave radio, military, space, telecomms infrastructure, test instrumentation and VSAT applications.

"The CMM4000-BD is well suited as a buffer stage for wide bandwidth applications", stated Jeff Kovitz, Senior Product Manager, Mimix Broadband.

"The device is a single supply distributed amplifier with integrated bias coil, providing excellent input and output match coupled with a flat gain response across frequency".

"Solid performance over temperature makes this device an ideal addition to any multistage amplifier application".

Mimix performs 100% on-wafer DC testing and 100% RF wafer qualification, as well as 100% visual inspection to MIL-STD-883 method 2010.

The chip also has surface passivation to protect and provide rugged parts with backside via holes and gold metallisation to allow either a conductive epoxy or eutectic solder die attach process.

Production quantities are available today from stock.
