I am currently attempting to build a Bi-Directional RF
amplifier for the 2.4GHz band, I am basing my design on 4
ERA-4 Monolithic Amp IC's (2 chains of 2 cascaded ERA-4's)
and I am trying to find a method for couple the output of
one chain and the input of the other to one antenna and vice
versa at the other end, the problem however is that I can't
Direct couple them otherwise I'll have a feedback loop that
will quickly destroy the circuit,
i.e.:

--ANT ANT--|ERA-4>-

It is for a Wireless LAN Repeater (802.11b).
Please email any replies to me
