4209-18-31.5 RF Variable Attenuator by Spectrum Control

The Model 4209-18-31.5 from Spectrum Control is a Solid-State Programmable Attenuator that operates from 0.1 to 18 GHz. It has an attenuation range of 0 to 31.5 dB in 0.5 dB step size with an attenuation accuracy of ±0.4 dB. This attenuator has an insertion loss of 2.3 dB and a switching speed of less than 6 µs. It can handle an input power of +28 dBm and has a VSWR of less than 2.0:1. This attenuator provides excellent solid-state repeatability with very fast attenuation switching and fine attenuation step resolution.

The Model 4209-18-31.5 can be remotely controlled via an AUX connector in parallel (TTL compatible) or serial (I2C/SPI/UART interfaces) mode, or through a USB Mini-B interface. This programmable attenuator requires a DC supply of 3.5 to 16 V and consumes less than 25 mA of current. It is available as a module that measures 65.93 x 76.20 x 13.72 mm and has SMA (female) connectors. This RoHS-compliant attenuator is ideal for automated test equipment, MIMO/WiMAX/Wi-Fi, 2G/3G/4G/5G fading simulators, and production test labs.
