1 to 20 GHz SDLVA module features 250 V ESD rating

Hittite Microwave Corporation has introduced a Successive Detection Log Video Amplifier (SDLVA) that operates over the full 1 to 20 GHz frequency range and carries a class 1A ESD rating (250V HBM).

Specified as an improved ESD performance replacement for the HMC-C052 SDLVA, the HMC-C088 features miniature connectorized module packaging, which make it ideal for designers with space and power-constrained applications including EW and ELINT receivers, DF radar, ECM, and IFM systems.

Also ideal for pulsed signal applications requiring high amplitude accuracy, the HMC-C088 is a broadband SDLVA device that converts RF signals at its input to an output voltage that is proportional to the logarithm of the RF input signal amplitude. It employs a successive compression topology, which delivers a high logging range of 59 dB and allows for the processing of high level signals up to +5 dBm. During typical operation, the SDLVA provides a nominal slope of 14 mV/dB and a typical intercept of -119 dBm at 10 GHz.

The HMC-C088 also provides high value for laboratory and high reliability applications and is capable of processing RF pulses with amplitudes from -54 dBm to +5 dBm with less than 10 ns rise/fall times, and with only 21 ns of recovery time. It exhibits frequency flatness of better than ±2 dB at -30 dBm input power, while logarithmic linearity is less than ±1 dB. The HMC-C088 features an integrated voltage regulator that allows operation from a single supply voltage between +7 V and +16 V without any appreciable change in performance. The SDLVA draws significantly less power compared with competing discrete and module SDLVA solutions, consuming only 1 W from a +12 V supply.

The HMC-C088 is supplied standard with two female SMA field replaceable connectors, but can also be used with blind mate SMP connectors or as a drop-in module. Specified for operation over the full -55 °C to +85 °C temperature range, the SDLVA is housed in a miniature connectorized package with 1.086- x 0.85- x 0.23-inches (27.58 x 21.6 x 5.84 mm) dimensions.
