Hittite has released two new chip and SMT GaAs pHEMT MMIC power amplifiers (PAs) for military EW, space, and test and measurement equipment applications from DC to 22 GHz.
The HMC797 is a 1 Watt chip which is rated from DC to 22 GHz, and delivers 14,5 dB gain, +31 dBm saturated output power, and +40 dBm output IP3. It also exhibits a positive gain slope from DC to 22 GHz, making it well suited to subsystems applications. The chip consumes 400 mA from a +10 V supply and occupies only 4,48 mm².
The HMC907 is self-biased and is rated from 0,2 to 22 GHz. It delivers 14 dB of gain, +20,5 dBm saturated output power, and +38 dBm output IP3. Gain flatness is ±0,6 dB from DC to 12 GHz. The IC consumes 350 mA from a +10 V supply and occupies only 3,87 mm².
Both chips feature RF I/Os that are matched to 50 Ω, which facilitates integration into multichip modules (MCMs).
