The HMC346C8 is an absorptive Voltage Variable Attenuator (VVA) from Hittite Microwave that operates from DC - 8 GHz and has a 30 dB attenuation range. It is ideal for basestation infrastructure, fiber optics & broadband telecom, microwave radio & VSAT, military radios, radar, & ECM, and test instrumentation applications.
The HMC346C8 is a GaAs MMIC surface-mount voltage-variable attenuator (VVA) designed for operation from DC to 8 GHz. It features an on-chip reference attenuator and is housed in a non-hermetic surface-mount ceramic package. The device is suitable for applications requiring analog DC control of RF signal levels over a 30 dB amplitude range, such as AGC circuits and temperature compensation in microwave radios and test instrumentation.
