Claim 8:
9. The amplifier of claim 1, wherein the reactance network comprises a series resonator comprised of a balun with one of its balanced ports connected to the control port of the circulator and another balanced port connected to output terminals of the negative resistance network and an unbalanced port connected to a transmission line which has a characteristic impedance Z01 and length L1, terminated in a short circuited transmission line which has a characteristic impedance Z02 and length L2, such that series connected transmission line terminated in a short circuited transmission line presents a short circuit at its input at frequency F0; and
a shunt resonator connected to the output terminals of the negative resistance network which is comprised of a shunt connected transmission line which has a characteristic impedance Z03 and length L3, and is terminated in an open circuited transmission line which has a characteristic impedance Z04 and length L4, such that the shunt connected transmission line terminated in the open circuited transmission line presents an open circuit at its input at frequency F0 connected to the output terminals of the negative resistance network.
