Model AM1650DC836 is a compact coaxial directional coupler from Anatech Electronics designed for applications from 800 to 2500 MHz. It suffers only 0.5-dB insertion loss over that span, with 13-dB nominal coupling and 20-dB directivity. The directional coupler provides 40-W power-handling capability in a housing measuring just 4.2 x 1.4 x 0.9 in. with Type N male or female connectors. It exhibits 1.20:1 maximum VSWR and achieves -140-dBc intermodulation-distortion (IMD) performance from -30 to +60°C.
