GaAs pHEMT amplifiers extend RF gain coverage
Two high linearity gain blocks extend the portfolio available from Guerilla RF. The additions include a full suite of gain options. The GRF2010 and GRF2011 target infrastructure applications such as 5G/4G base stations, automotive telematics, and cellular repeaters / DAS (distributed antenna systems).
These new cores extend the gain coverage for Guerilla RF’s existing portfolio of general-purpose RF/microwave gain blocks. When used in conjunction with the company’s GRF2013, customers have a choice of devices offering nominal gain levels of 10dB, 15dB and 18dB. In addition, the entire set of components is drop-in compatible with Guerrilla RF’s corresponding collection of gain blocks with bypass, the GRF2040, GRF2042 and GRF2043.
Ryan Pratt, CEO and founder of Guerrilla RF, said: “Since these devices utilise our popular 1.5 x 1.5mm DFN-6 package, designers can quickly modify existing hardware to support new bands and line up requirements. Each of these DFN-6 modular cores can be easily swapped out to yield different levels of gain, linearity and noise figure,” he added. These are all critical parameters that define a radio’s overall performance and spec compliance. “In today’s highly competitive business environment, this flexibility gives our customers a significant edge when pivoting to chase new design opportunities,” added Pratt.
The entire series of gain blocks provides exceptionally flat gain and flexible biasing options, claimed the company, making them suitable for high levels of re-use within a single design and across multiple platforms. When using a nominal 5V bias and single match covering 400 to 4000MHz, the GRF2010 draws 90mA of current while delivering 10dB of gain, 36dBm of OIP3 linearity, a compression level of 20dBm, and a noise figure of 3.1dB. The GRF2011, with a single match tune of 700 to 3800MHz, increases the gain offering to 15.2dB, with 40dBm of OIP3 linearity, 22.7dBm of OP1dB compression, and an even lower noise figure of 2dB. Both devices can be tuned to operate over lower frequencies reaching down to 50MHz.
Samples and evaluation boards are available for the GRF2010 and GRF2011.
