Features:
1. Covers three frequency bands: 400-600MHz, 500-700MHz, and 600-800MHz, with uplink and downlink operating in the same band.
2. Delivers downlink maximum output power of 43±1dBm and gain of 51±2dB, ensuring stable signal transmission.
3. Operates at 28V with a maximum current of ≤5A, featuring over-temperature protection (shutdown at 85℃, restart at 65℃).
4. Boasts excellent performance indicators: EVM ≤5%, VSWR ≤1.4, and transmit-receive isolation ≥55dBc.
