Product parameters
| Performance parameters | Indicator data |
|---|---|
| Frequency range | 30MHz～88MHz |
| Input and output test port impedance | 50Ω |
| Power amplifier drain power consumption | ≤200W (drain voltage: 24V) |
| Output power and gain | Output power: 49dBm, gain ≥18dB (gain ≥17dB under environment) |
| Input signal | When the input signal power of each RF port is ≤40dBm, the module will not be damaged |
| Broadband noise | In the frequency band of 30MHz to 88MHz, when the output power condition is met, the signal source noise (input excitation noise) is -154dBm/Hz, and the output RF port deviates from the carrier frequency by 10% (not less than 5MHz) ≤-120dBm/Hz |
| Linearity | 30MHz to 88MHz: The modulation mode is constant envelope modulation, and the adjacent channel power ratio is ≤-25dBc. Test method: When the RF port output reaches 49dBm, QPSK modulation is added to the input end, roll-off coefficient 0.25, 40K symbol rate, 50K deviation from the center |
