Accurate wideband connectorised digital attenuator module
New from RF and microwave component specialist Link Microtek is a GaAs MMIC-based connectorised digital attenuator module that provides excellent accuracy over its wide bandwidth of DC to 13GHz.
Manufactured by Hittite Microwave Corporation, the HMC-C025 is a 6-bit digital attenuator with bit values of 0.5 (LSB), 1, 2, 4, 8 and 16dB, providing a total attenuation of 31.5dB. The device has a typical attenuation accuracy of +/-0.3dB, a typical insertion loss of 4dB and an input IP3 of +38dBm.
The Housed in a hermetically sealed module, the HMC-C025 attenuator has an operating temperature range of -55 to +85degC and is particularly suitable for applications in military radio, radar, ECM and space systems.
