Multiplier modules

Hittite has introduced four active x2 frequency multiplier modules that provide output frequency coverage from 6 to 46 GHz.

Each one provides high output power and fundamental subharmonic suppression for microwave communications, radar, test equipment and general laboratory applications.

The HMC-C031, HMC-C032, HMC-C033 and HMC-C034 use GaAs PHEMT technology and are packaged in miniature hermetic 41.66 x 27.59 x 8.50 mm connectorised modules.

When driven with a +3 dBm signal, the multipliers deliver between +13 and +17 dBm of output with Fo and 3Fo isolations from 12 to 30 dBc with respect to the output signal level.

They are suitable for LO multiplier chains, exhibiting SSB phase noise to -140 dBc/Hz at 100 kHz offset. They incorporate DC blocked I/Os as well as overvoltage and reverse voltage protection.
