Details
Manufactured by HIROSE (HRS) as their part number HDH-02003DHD-DC, this is an industry standard 2 way directional coupler with SMA female connections.
Hirose HDH directional couplers offer extremely low loss, a high degree of matching and high isolation. 1 input and 2 output (or vice versa) with 90 degree phase difference between input and output.
The manufacturers datasheet - address at bottom of this page, states the useful frequency range as been 1.7GHz to 2.3GHz, the actual units have 1.8 - 2.2 marked on them.
VSWR is 1.20:1 or better, 0.3 dB Insertion Loss and 20 dB or better isolation, 3dB coupling, rated upto 2W.
Offered here at a fraction to the distributors list price, good condition - removed from brand new equipment which had to be dismantled under a secure destruction order.
