Hermetic SMT MMIC components cover DC to 15.5GHz
Hittite Microwave has announced four products that use its high frequency LH5 leadless hermetic SMT package, which is ideal for high reliability, space and military applications.
The HMC441LH5 is a 7 to 15.5GHz GaAs MMIC medium power amplifier, providing 15dB gain and +21.5dBm of saturated power at 25% PAE. This 50ohm matched amplifier requires no external components, and the internally DC blocked RF I/Os make this an ideal linear gain block or driver amplifier. For up-convertor and down-convertor applications from 7 to 14GHz - the HMC141LH5 - is a passive double-balanced mixer featuring LO to RF and LO to IF isolations of 35dB, IF bandwidth of DC to 2GHz, and input IP3 of +23dBm.
The HMC424LH5 6bit GaAs MMIC digital attenuator is rated from DC to 13GHz, and provides monotonic attenuation from 0.5 to 31.5dB, in 0.5dB steps.
The HMC424LH5 requires a single control line per bit and offers excellent attenuation accuracy of +/-0.3dB.
The HMC344LH5 is a non-reflective GaAs MMIC SP4T switch featuring 42dB isolation, and 1.8dB insertion loss.
The HMC344LH5 is rated from DC to 12GHz, and the integrated decoder requires only two control lines.
Screening to Mil-PRF-38535 (Class B or Class S) is available on each of the above products.
