    Any book about practical LNA design

    POZAR is very good book for general microwave systems. Gonzales is focus on LNA so its better for that purpose.

    multi-carrier problem in PA [hlp]

    Multi Carrier modulations like OFDM needs good linearity. Sometimes all the carriers came in phase and sometimes out of phase. So this kind of modulation has large PEAK to AVAREGE. this is the reason the amplifier should be vary linear. Linearizations are very popular for this kind of...

    How to check power amplifier's class?

    Re: PA class I know my VGS and VDS. I am using ST PD0015 device. VGS = 4.7V VDS = 12V what more i need to check ? how can i simulate the conduction angle ? noise

    How to check power amplifier's class?

    I design my power amplifier. I just want to know what is the class of my amplifier. I think its AB but not sure. what is the parameters I need to simulate for verify the class ? What i need to check ? I am using ADS. thanks Noise.

    About transmission line transformers

    I want to build my own transmission line transformers. It will be use with push pull amplifier configuration (balun). my quastion is how to select the AWG for the twisted pair wires ? The max output power is 25W and the impedance ratio is 1:9. Thanks, Noise

    Effect of limiter on BER

    Hello all, I am trying to simulate the effect of RF Limiter on QPSK and 8PSK. I compare the results against theoretical curve for BER to Es\No. the problem is, i got the same degradation from theoritical curve at Qpsk and 8PSK , something about 1dB. The 1 dB degradation is between the...
