HMC985ALP4KE

RF Variable Attenuator by Analog Devices

Note : Your request will be directed to Analog Devices.

The HMC985ALP4KE from Analog Devices is a GaAs MMIC Voltage - Variable Attenuator that operates from 10 to 40 GHz. It provides an attenuation range of up to 42 dB and has an insertion loss of less than 4 dB. The attenuator can handle an input power of up to 30 dBm and has an operating temperature range from -40°C to +85°C. It features two shunt-type attenuators which are controlled by two analog voltages, Vctl1 and Vctl2. Optimum linearity performance of the attenuator is achieved by first varying Vctl1 of the first attenuation stage from -5V to 0V with Vctl2 fixed at -5V. The control voltage of the second attenuation stage, Vctl2, can then be varied from -5V to 0V with Vctl1 fixed at 0.

The HMC985ALP4KE is available in a 24-lead, surface-mount package that measures 4 x 4 mm and is suitable for use in point-to-point radios, VSAT radios, test instrumentation, microwave sensors and military, ECM & radars.
