Designer Kits

 Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced an industry first Successive Detection Log Video Amplifier (SDLVA) that operates over the full 0.1 to 20 GHz frequency range. Available extremely compact 4x4 mm surface mount and miniature connectorized module packaging, the HMC613LC4B and the HMC-C052 are 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 HMC613LC4B represents the first in a new family of broadband SDLVA devices from Hittite that convert RF signals at their input to an output voltage that is proportional to the logarithm of the RF input signal amplitude. The HMC613LC4B employs a successive compression topology, which delivers a high logging range of 62 dB and allows for the processing of high level signals up to +3 dBm. During typical operation, the HMC613LC4B provides a nominal slope of 14 mV/dB and a typical intercept of -119 dBm at 10 GHz.

The HMC613LC4B is capable of processing RF pulses with amplitudes from -57 dBm to +5 dBm with less than 10 ns rise times, and with only 26 ns of recovery time. The HMC613LC4B exhibits frequency flatness of better than   ±2 dB at -30 dBm input power, while logarithmic linearity is less than ±1 dB. Specified for operation over the -40 to +85°C range, the HMC613LC4B also provides Tangential Signal Sensitivity (TSS) of -64 dBm at 25°C, and consumes only 260 mW from a single +3.3V supply.

For high reliability, laboratory and military applications, the HMC-C052 hermetic, connectorized, wideband SDLVA module is now available. The HMC-C052 operates from 1 to 20 GHz with a logging range of 59 dB, and exhibits frequency flatness of ±2 dB at -30 dBm input power. Specified for operation from -55 to +85°C, the HMC-C052 delivers a TSS of -67 dBm.

Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
