300MHz 60W Extended Range RF Power Amplifier Support Half-duplex Working Mode 12-15V Power Amplifier
Description:
- The main function is to amplify the low-power signal of the original 285-315MHz device, increase the power of the signal, and enable the small device to have high power, making the communication distance longer and the voice clearer, expanding the coverage range. It has an internal automatic transmission and reception conversion circuit for transmission and reception switching, suitable for handheld U-band walkie talkies and data transmission devices on the market, and can also be tested with various one-way data transmission radio stations and wireless equipment, electromagnetic compatibility testing, etc.
Specification:
- Working frequency: 285 - 315MHz
- Input power: 1 - 5W (general handheld walkie talkie)
- Receiving frequency: 50 - 1000MHz
- Working mode: half-duplex (cannot receive in transmission state)
- Receiving loss: 0.5dB (can be ignored)
- Output power: 60W (typical value)
- Power supply voltage: 12 - 15V (typical value 13.8V)
- Working current: 15A (typical value)
- Standby current: about 50mA (power supply is not required for receiving)
- Heat dissipation method: 40℃ intelligent temperature controlled air cooling
- Product size: 135 x 120 x 90mm
- Net weight: 680g
Package Included:
- 1 x RF Power Amplifier
Note:
- Prohibit power on operation when there is no-load or a serious mismatch of load.
- Before use, all instruments and equipment should be grounded together (without any potential difference), and then connected with RF cables. They must be connected to the load and must not be used without load.
- Be sure to use a "legitimate" antenna, especially when using the antenna as a load, and ensure that the impedance of the antenna matches within the operating frequency (generally requiring a voltage standing wave ratio of less than 2.0). It is strictly prohibited to use "illegitimate" antennas, such as rod antennas, copper wire antennas, and cheap antennas, which have no definite impedance.
- Try to use linear power supplies as much as possible, especially when using low-noise amplifiers, be sure to use linear power supplies or batteries. Switching power supplies themselves have a lot of noise, which can enter the amplification circuit. Do not use switching power supplies.
