The GLSL series of surface mount direction couplers can be used for RF circuitry, broadband, mobile radio, and satellite TV technologies. The compact design is on a ceramic base. Model number GLSL20D102 is a 20 dB coupler operating from 1 MHz to 1 GHz. Typical insertion loss is less than 0.5 dB from 2 MHz to 1 GHz. Directivity typically exceeds 10 dB from 1 MHz to 1 GHz. Operating temperature range is 40°C to +125°C. This coupler is suitable for automatic insertion on surface mount circuits assembled using reflow or vapor phase soldering. Soldering heat resistance is 230° for 5 s.
