MMICs address high-reliability applications

Link Microtek has a family of MMIC components in LH5 leadless hermetic SMT packages, making them ideal for use in high-reliability applications in the space, industrial and military sectors.

Now available from RF and microwave component specialist Link Microtek is a family of MMIC components manufactured by Hittite Microwave Corporation and supplied in LH5 leadless hermetic SMT packages, making them ideal for use in high-reliability applications in the space, industrial and military sectors.

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 it an ideal linear gain block or driver amplifier.

For upconvertor and downconvertor 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 covers the frequency range from DC to 13GHz and provides monotonic attenuation from 0.5 to 31.5dB, in 0.5dB steps.

This device requires a single control line per bit and offers excellent attenuation accuracy of +/-0.3dB.

The HMC344LH5 is a nonreflective GaAs MMIC SP4T switch featuring 42dB isolation and 1.8dB insertion loss.

It operates over the frequency range DC to 12GHz, and its integrated decoder requires only two control lines.

Screening to MIL-PRF-38535 (Class B or Class S) is available on all of the products.
