40db RF Attenuator for PM3A

 

HF 40db attenuator is basically designed for PM3A RF Power Meter. However, it may be effectively used for other measuring purposes.

 

 


PIC16F84A LCD L/C Meter: FD-LCM

Under Development

This is a 1x16 LCD L/C meter project using PIC16F628A. L/C Meter is built on a PTH PCB and measures C & L with very reasonable accuracy.

 

 


PIC16F877A LCD HF 100W SWR Meter: FD-SWR-HF

This 100W HF 2x16 LCD SWR Meter uses advanced PIC16F877A and have accurate RF Measurement pick-up board using a toroidal indictor bridge. Has back-lite control and simple two button menu operation. 

Meter displays Forward, Reflected, actual power to antenna and SWR.

 


PIC16F88 LCD VHF SWR METER : FD-SWM-VHF

This 2x20 LCD HF/VHF SWR Meter measures & Display SWR and Forward power and has a bar graph too. Uses PIC16F88 with inbuilt 8MHZ Osc. and has 3 front panel buttons for menu control.

Uses standard PL/SO239 sockets. 

 


PIC 16F876A 500MHZ Dual Channel RF Power Meter with Data Logger: PM3

PM3 is a version of PM2 with Data Logger Output and supports remote LCD & Menu Button placement. 

PM3 has a remote Sensor Board:

 


A Simple AD8307 RF Power Meter: FD-PM1

 

Coming soon

 

This is a simple AD8307 based 500MHZ RF Power meter which uses 10 LEDs  giving 10db step reading from -80db to +10db. Uses a LM3914.

 

 


RF Dummy Load 50 Ohms 10W

 

 

Resistive dummy load for 50 ohms will handle approx. 10W and has detector output for measurement
