CA-88E

Microlab CA-88 series hybrid 2×2 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.
