Product Description

Microlab CA-88 series hybrid 2x2 couplers have been designed for mobile networks that require combining signals in the 617 to 2700 MHz band. It is most commonly used to combine two wireless carriers cost-efficiently without a guard band to a single antenna feed or distribution cable. It requires terminating one output port and results in a 3 dB loss in each input signal. Both outputs may be used when two similar feeds are required, eliminating the need for a termination and the 3 dB coupling loss. For low PIM terminations, see the Microlab TK series. Mechanically CA-88 series is designed with passivated aluminum housings, moisture sealed to meet IP67. Connectors are spaced to allow controlled wrench tightening.
