Soldering Project KIT

 

 The SWR meter or VSWR (voltage standing wave ratio) meter measures the standing wave ratio in a transmission line. The meter can be used to indicate the degree of mismatch between a transmission line and its load (usually a radio antenna), or evaluate the effectiveness of impedance matching efforts.

  

   Features of SWR

- Minimum parts and ease of Assembly (no setup required)

- Input voltage from the measuring line: 0..5V.

- 2 segment LED

- High-performance processor ATMEGA48, which allows you to instantly display the latest information on the indicator.

- Power supply unit 5V. Consumption is about 10-15 mA.


----------------------------------------------------
Transmission line's parameters:
- Range: 1-30 MHZ and 144...146 MHZ
- Max RF power: up to 200W for 1..30MHZ version
   and 100Watt for board 144..146MHZ



SWR meters measure the impedance match between a transmitter and the output load. If the load differs from the reference impedance then ‘standing waves’, i.e. peaks and drops in RF voltages, will be present in the transmission line between the transmitter and the antenna. The ratio of the peak to minimum RF voltage is displayed on the SWR meter, referenced to the transmission line’s characteristic impedance, usually 50 ohms.

 

We offer SWR meter + Transmission Lines for 1..30 MHZ and 144..146MHz in All-in one package or can place the order to any kit separately.
