[AMSAT-BB] 2 meter amplifier on satellites

WIll most 2 meter amplifiers pass a UHF signal on receive when the amp is on?  I am wondering about using a 2 meter amplifier for Mode J satellites, where you transmit on 2m and receive on 70cm.  Will the filtering in most amps severely degrade the receive signal on UHF?
