Low Noise Amplifier and Power Amplifier

时间:04-07 整理:3721RD 点击:
I want to design a Low Noise Amplifier at frequency 435 MHz and Power Amplifier at 145 Mhz?
If you want a schematic, PCB board, please help me?

High Frequency LNA schematics

UHF GasFet LNA

Thanks for your information,
if you can already format sch (eagle software or ect) or
for design simulation with Ansoft Designer, AWR and ADS, ect...

thanks

Try to choose some transistor, like BFP740, check datasheet, applications
SPICE model as well as for the S-parameters on the producer internet website.
See for example:

Thanks so much..
but i need example PCB board Layout for LNA 435 Mhz?
use Eagle or etc?

See here, page 15

From this one example, may be i'm wrong but the RF path seems to be open between L1 and L2 (?), is it using coupled lines?


Yes, coupled lines...
