Recent improvements on the CMOS Silicon process introduced many one-chip solutions to the market. DSP, Analog/Digital converter, Digital/Analog converter, Up/Down converter, VCO and PLL Synthesizers are one of those one-chip solutions in the market today. However, CMOS has some drawbacks in higher power levels of 10dBm+ and having a high noise figure.
Sirenza Microdevices' SNA-600 is a high-performance GaAs Heterojunction Bipolar Transistor in die form. A Darlington configuration is utilized for broadband performance to 6.5 GHz.
Mimix Broadband’s three stage 11.0-16.0 GHz GaAs
MMIC power amplifier is optimized for linear operation
with a third order intercept point of +38.5 dBm. This
MMIC uses Mimix Broadband’s 0.15 µm GaAs PHEMT
device model technology, and is based upon electron
beam lithography to ensure high repeatability and
uniformity
The MMA-022030B is a 2 - 20GHz broadband MMIC power amplifier with nearly 1W output power (P-2dB). It is realized in
advanced AlGaAs/InGaAs pHEMT technology. The usable frequency range extends to 1 – 22 GHz. With on-chip
input/output blocking capacitors and DC supply RF choke circuitry, it only requires simple DC bias circuits and RF
connections for broad range applications
