LNA with ATF 54143
|On the left picture you can see both versions of LNA 432 and 1296 MHz||This is graph of IP. I got the picture from Franta OK1CA. He
has very nice double ton high level signal generator AGILENT E4432B and
HP 8093E noise measurement equipment.
Parameters on 1296 MHz: Pin -22dBm, Pout -5dBm, IMD3 -62dBm, Gain 17dB, +/-10kHz
|This is 432 MHz LNA. N/F 0,32dB and gain 20dB. Input IP +8dBm. I have tested this LNA also during last UHF - SHF EU contest with excellent result. PCB is done from FR4 PCB material with soldering holes for both versions.||This is version for 1296 MHz. N/F 0,4dB gain 17dB and input IP +9dBm !!! Also this type of LNA I have tested during EU SHF contest 2006 with excellent result. Specially high IP in combination with inter-digital filter bring lot of advantages in the battle with interference.|
