Applications:
- This amplifier could works with wide frequency range, which with stable gain, small noise , and large dynamic range (+19.5dBm/1dBP). It is especially suitable for various RF receiving front-end circuits and increases communication distance! Widely used in short wave, FM radio, remote control receiver, cable TV signal amplifier, Beidou, GPS satellite navigation, 2.4G Bluetooth, WIFI receiver RF front-end and other places that require low-noise small-signal RF amplification! The amplifier has a shielded enclosure with anti-reverse protection diodes
Specification:
- Power supply voltage: 5V DC (typical current value I <150mA)
- Gain: 40DB input and output impedance: 50 ohms
- Maximum output power: 19dBm (under 6VPP \ 50 ohm load)
- Input signal: <-20dBm (the output signal is distorted when the input is greater than -20dBm)
- Bandwidth: 20MHz to 3GHz (the gain is different at different frequencies, please refer to the S21 curve index for details)
- Noise figure: 1.3dB (measured at 1.5GHz)
- With metal shell shielding
