Hittite Microwave has introduced four products in its new high frequency LH5 leadless hermetic SMT package, suited for high reliability, space and military applications. The HMC441LH5 is a 7 to 15,5 GHz GaAs MMIC medium power amplifier providing 15 dB gain and +21,5 dBm of saturated power at 25% PAE. This amplifier requires no external components, and the internally-DC blocked RF I/Os make it an ideal linear gain block or driver amplifier. For up- down-conversion from 7 to 14 GHz, the HMC141LH5 is a passive double-balanced mixer featuring LO to RF and LO to IF isolations of 35 dB, IF bandwidth of DC to 2 GHz, and input IP3 of +23 dBm. The HMC424LH5 6-bit GaAs MMIC digital attenuator is rated from DC to 13 GHz, and provides monotonic attenuation from 0,5 to 31,5 dB, in 0,5 dB steps. The HMC344LH5 for DC to 12 GHz, is a non-reflective GaAs MMIC SP4T switch featuring 42 dB isolation, and 1,8 dB insertion loss.
