Directional Couplers for Wireless Band Applications
MECA's V-Line, 715-dB-1.400 directional couplers are designed to cover all wireless bands from cellular through PCS (0.800 GHz - 2.000 GHz). Insertion loss is less than 0.1 dB, VSWR is 1.15:1, and coupling accuracy is 1.5 dB. Directivity is maintained at 25 dB.
The 715-dB-0.900 is designed for cellular/GSM applications (0.800 GHz - 1.000 GHz) and offers insertion loss of less than 0.1 dB, VSWR of 1.10:1, directivity of 30 dB and coupling accuracy of 0.6 dB over the band. Couplers in this series are usable from 0.600 GHz - 1.200 GHz.
The 715-dB-1.950 is designed for the DCS/PCS/UMTS bands (1.700 GHz - 2.200 GHz) and exhibits insertion loss of less than 0.1 dB, VSWR of 1.10:1, directivity of 25 dB and coupling accuracy of 0.6 dB over the band. The couplers in this series are usable from 1.300 - 2.600 GHz.
All couplers are furnished with brass N-female connectors, gold plated contact pins, virgin electrical grade Teflon( insulation within the connectors and rugged aluminum housings. Operating temperature is from -65°C( to +150°C. Coupling values of 6 and 10 dB are rated for 100 watts average (10 kW peak) and the 20 - 50 dB couplers are rated for 500 watts average (10 kW peak) with low passive intermodulation of -140 dBc.
