Gain Block Amplifiers


The range of line amplifiers from GPS Networking operates in the GPS L1, L2, L5, GLONASS, and Galileo frequency bands with excellent gain flatness. These amplifiers are configured with one input and one output, with a nominal gain block of 20, 25, or 30 dB. 

Guerrilla RF Inc. offers two new models of high linearity gain block amplifiers featuring a combination of simple-application schematics, flat gain, and high compressed output power with operation in the DC to 4 GHz frequency range. The GRF2012 and GRF 2013 models include flexible biasing for high levels of re-use within single designs and multiple platforms. They are ideally used as cost-effective pre-drivers for broadband GaN high power amplifiers, and for many other general purpose, high performance gain block applications.

The CGB8002-SC is a single stage, high power, high dynamic range, utility gain block amplifier. Designed for 3.3V applications operating within the DC to 2.8 GHz frequency range, Mimix’s broadband, cascadable, gain block amplifier is an ideal solution for transmit, receive and IF applications. This MMIC amplifier is available in an industry standard, RoHS compliant, SOT-89 package. Mimix's InGaP HBT technology and thermal resistance offers a thermally robust and reliable gain block solution.
The 40MHz - 2600MHz Flat Gain High Linearity Gain Block: MGA-30889 from Avago Technologies is a broadband, flat gain, high linearity gain block MMIC amplifier achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process.

Qorvo offers the QPA9154 wideband gain block with a 50 Ω single-ended input to 100 Ω differential output. It is ideally suited as the 5G m-MIMO BTS Rx path final gain stage, to directly interface with the ADC of the transceiver, eliminating the need for a discrete balun.

Avago Technologies’ new Broadband High Linearity InGaP HBT Gain Blocks: AVT-51663/AVT-53663 are economical, easy-to-use, general purpose InGaP HBT MMIC gain block amplifiers utilizing Darlington pair configuration housed in a 6-lead (SOT-363) surface mount plastic package.

The AVT-51663 and AVT-53663 are ideal devices for small-signal gain cascades or IF amplification.

Celeritek’s CGB7010-BD is a Darlington Configured, high dynamic range, utility gain block amplifier MMIC chip.
Celeritek’s CGB7001-BD is a Darlington configured, high dynamic range, utility gain block amplifier MMIC chip. It is matched to 50-W impedance for both input and output from 0.1 to 6.0 GHz
