RFMD expands portfolio with best-in-class microwave voltage-controlled attenuator

USA: RF Micro Devices Inc. has released the RFSA2113, a broadband, microwave voltage-controlled attenuator.

The RFSA2113 provides a complete monolithic solution in a small 3mm x 3mm QFN package and operates over a frequency range of 50MHz to 18GHz.

The RFSA2113 also incorporates a new circuit architecture that offers high IP3, high attenuation range, low DC current, broad bandwidth and a temperature compensated linear-in-dB control voltage characteristic.
The attenuator's temperature-stable operation allows for the elimination of off-chip calibration and correction circuitry, reducing both cost and DC power requirements.

Real world applications for the RFSA2113 microwave voltage-controlled attenuator include wireless backhaul, test instrumentation, military and satellite communications.
