Akozon RF Signaal Power Module Meter Logaritmische Detector Hoge frequentie -74dBm naar 18dBm Radio Frequency Detection

Alles in BESTER Ordnung!

The module works in principle.However the input port has wrong component values. The resistor is 100 Ohms but should be 52.3 Ohm according to Analog Devices AD8307 application note.So the installed 100R resistor needs to be replaced - in my case by 2 x 100R in parallel. Not perfect but ok for my needs.Then there is also a 100nF capacitor in series with the input port. This capacitor is completely unnecessary acc. to mentione application note and can only worsen the broadband behaviour of the module.So this capacitor was remover and replaced by a wire.After this SMD soldering the modules now have 50 Ohm input impedance.
