| Abstract: | This paper describes a solid S-band highly linear power amplifier by using push-pull configuration and broadside coupled lines power combiner.The push-pull configuration makes the amplifier easier to match,and the broadside coupled lines power combiner can handle high power.Accordingly the flat response of the amplifier's high linear output power is realized.Within 90 MHz bandwidth of the S-band,the amplifier provides a gain of 68±0.5 dB,a linear output power of 300 W,and an IM3 of the output signal ≤-45 dBc. |
