Buffer amps provide broadband operation

Edited by the Electronicstalk editorial team Mar 5, 2007

Buffer amplifiers are ideal for wireless communications applications such as millimetre-wave point-to-point radio, local multipoint distribution services, satcom and Vsat applications.

Mimix Broadband has released two gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) two stage buffer amplifiers.

Using 0.15um-gate-length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, the XB1007-BD and XB1008-BD, cover 4-11 and 10-21GHz, respectively.

Both devices deliver +20dBm P1dB compression point and +30dBm OIP3.

The XB1007-BD has a noise figure of 4.5dB and 23dB small signal gain; the XB1008-BD has a noise figure of 5.5dB and 18dB small signal gain.

These buffer amplifiers are ideal for wireless communications applications such as millimetre-wave point-to-point radio, local multipoint distribution services (LMDS), satcom and Vsat applications.

"These two buffer amplifiers offer a combination of broadband operation, output power and compact dimensions to provide a cost-effective solution for frequencies from 4 to 21GHz", stated Paul Beasly, Product Manager of Mimix Broadband.

"The compact 1.2mm2 die with wideband return loss operation is consistent with broadband use in a variety of frequency and functional applications".

Packaged versions of the XB1007-BD and XB1008-BD in fully moulded, plastic 3x3 QFN packages will be available in the near future for surface mount applications.

Samples are available today from stock, along with production quantities.
