The ACM2218 from KRATOS General Microwave is an Amplitude Control Module that operates from 2 to 18 GHz. It provides precise control of signal amplitude and pulse modulation over a high dynamic range with very fine resolution. The device delivers a P1dB of 15 dBm with a gain of more than 14 dB and provides isolation of more than 90 dB. It has harmonics of less than -60 dBc, a switching speed of up to 1 µs, and a VSWR of less than 2.5:1. The ACM has a 10-bit TTL control and requires a DC supply voltage of +15 V while consuming up to 800 mA of current. The ACM2218 is available in a module that measures 134.6 x 76.2 x 26.7 mm with SMA male and female connectors.
