From the project

PCB for the AG203-63G wideband LNA (0-6GHz)

The PCB has a height of 0.6 mm, which is crucial (at least at higher frequencies) and it was ordered in China [2]. The populated PCB was soldered into a tinplate filter housing FG1 of size 37x20x20 mm [3]. To get the DC voltage into the housing a 1000 pF feed through capacitor DF 38 [4] was used.

The fully build amplifier has been characterized using an DG8SAQ VNA [5]. The input return loss is ca. 15 dB for 70 cm band (433 MHz) and ca. 21 dB for 2 m band (145 MHz). The data of the measurement can be found in the measurements folder. When you want to operate the LNA at a higher frequency, you…
