tunable rf filter design varactor
3xs tiff44
I want P1dB>25dBm
in my design,I have enough tuning range.
I don't know how to choose varactor to improve P1db.
in varactor datasheet , which character can illustrate the power_capacity of the varactor?
tunable filter varactor vhf
hi
i want to design the tunable LC filter using varactor in VHF, i choose BB809 in my circuit.
the input P1dB of the LC filter is 10dBm, can you tell me how to improve the input P1dB, how to choose the varactor to realize the high P1dB

wideband coupler help?
hello
I want to design a wide band coupler (100MHz-600MHz).But using microstrip circuit is too large.
so my question :
is there some coupler circuit can provide the flat response in this band.
another question:
if the term of the couple changed,(eg the term is 50ohm or...
