High performance combination for VSAT, PtP and radar markets

CHELMSFORD, ENGLAND: Hittite Microwave Corp. has announced a new GaAs pHEMT MMIC power amplifier and an analog variable gain amplifier that are ideal for Ka-band VSAT, high capacity microwave radio and radar systems in the 27.5 to 31 GHz frequency range.

The HMC7441 is a three-stage GaAs pHEMT Power Amplifier which operates between 27.5 and 31 GHz. The amplifier provides 23 dB of gain and +34 dBm of saturated output power at 25 percentage PAE from a 6V supply.

With an excellent output IP3 of +38 dBm, the HMC7441 power amplifier is ideal for linear applications demanding +34 dBm of efficient saturated output power. The RF I/Os are DC blocked and matched to 50 Ohms for ease of integration into MCMs.

The HMC6187LP4E is a GaAs MMIC pHEMT analog variable gain amplifier and/or driver amplifier which operates between 27 and 31.5 GHz and delivers excellent gain flatness. The HMC6187LP4E amplifier provides up to 19 dB of gain, +24 dBm output P1dB, and +31 dBm of output IP3 at maximum gain, while requiring 230 mA from a +5V supply.

Vctrl is provided to allow variable gain control up to 13 dB. The HMC6187LP4E is housed in a RoHS compliant 4 x 4 mm plastic QFN leadless package and is compatible with high volume surface mount manufacturing.
