Note : Your request will be directed to API Technologies.

The 4204-95.5 from API Technologies (Weinschel) is a Solid State Programmable Attenuator that operates from 35 MHz to 3 GHz. It has an attenuation range from 0 to 95.5 dB with 0.5 dB steps and has an insertion loss of less than 4.5 dB. This attenuator can handle up to 23 dBm of input power and has a VSWR of less than 2:1. It can be controlled using parallel (TTL & CMOS compatible), USB, UART, I2C, or SPI interfaces. The attenuator requires a 5 V of DC supply, consumes 30mA of current, and is internally matched to 75 ohms. It is available in a module that measures 69.6 x 59.18 x 19.4 mm with female connectors. It can be controlled via software that can be installed on Microsoft Windows, Apple OS X, or Linux systems.
