First, an overview:

RF260 is a radio frequency power module. Advantages: simple structure, easy to use, stable and reliable performance, high reliability, high sensitivity and fast measurement, etc..

Two, application:

The RF power measurement;

– meter calibration;

Three, technical parameter table:

Item parameter unit notes

1 measurement power range -65 ~ dBm +0 (external RF attenuator can be extended to 100dBm)

2 measuring power resolution 0.1 dBm

3 measurement frequency range 100 ~ 2400 MHz

4 measuring power 1nW ~ 100mW

5 working voltage 7 ~ 17 VDC

6 working current mA <50

7 size mm X long 52*34*10 wide X high

Output mode: circuit board on the S2 pad: open circuit (output 0.00V ~ 5.00V); short (output 10.00V ~ 0.00V), the default is open circuit.

Adjust the potentiometer RW1 to correct the output error, the correction range +/-5dBm.

P1 interface: radio frequency signal input. (SMA KE KHD RP external screw inner hole)

P2 connection definition:

Symbolic meaning of serial number

1 VDD module power supply cathode (7V~17V)

2 GND module power cathode

P3 connection definition:

Symbolic meaning of serial number

1 OUT output dBm voltage signal (0.00V ~ 5.00V/0.00V ~ 10.00V).

2 GND power cathode

Note: output 0.00V ~ 10.00V, the power supply voltage to 15 volts.

Output (0.00V ~ 5.00V) range (-80 ~ +20dBm); resolution: 0.050V/dBm

Output (0.00V ~ 10.00V) range (-80 ~ +20dBm); resolution: 0.100V/dBm

Calculate the measured dBm formula: (output voltage (V) / resolution) = dBm.

For example: output (0.00V ~ 5.00V) output is 2.5V

(2.5 (V) /0.05) -80dBm = -30dBm.
