High Power Dual Directional PCS Coupler with Lightning Protection 1850-1990 MHz CH20-0039-30 V2.00 Features ● ● ● ● ● ● 7-16 PLUG CONNECTOR 2.25 (57.2) M/A-COM’s CH20-0039-30 is designed to provide highly accurate power sampling of both transmitted and reflected power. This coupler operates over the full PCS transmit and receive bandwith of 1850-1990 MHz and is ideally suited for installation between the antenna cable and base station within a base station enclosure. Its integral lightning protection circuit offers affordable protection against the harmful current accompanying a tower or antenna cable lightning strike. The protection circuit is designed to be permanent, withstanding the largest strikes without need for element replacement. Stainless steel grounding hardware accommodates NEMA spaced ground straps. The appropriate plating and the absence of any ferrous material in the circuitry assures low intermodulation products. Air-line construction yields the lowest possible insertion loss and VSWR, allowing dual-directional monitoring without sacrificing base station performance. 1.85 (47.0) -30dB #10-32 THRU (4 PLS) Description 1.19 (30.2) .7 MAX (16.0) ANT ● Ultra Low Loss Integral Lightning Protection Accurate Coupling High Directivity Low VSWR High Power Handling Low Intermodulation products Operates over complete pcs Transmit/Receive Band -30dB ● 5.00 MAX (125.9) SMA JACK (2 PLS) 2.69 (68.3) REMOVABLE 50 OHM TERMINATION (2 PLS) 7-16 JACK CONNECTOR GROUNDING HARDWARE (2 PLS) (Dimensions in parenthesis are in mm) If continuous power monitoring is necessary, the CH20-0039-30 can be supplied without the removable 50 Ohm terminations on the SMA sample ports. This device can be provided without lightning protection or with N type connectors on the primary line. Please consult the factory.
