FAQ
Q1: What does “2×5 W” mean in the model name? UN: It indicates dual transmit capability with up to 5W (37 dBm) output power per channel, supporting 2T2R (dual transmit, dual receive) configurations.
Q2: How is the TDD switching controlled? UN: Via TTL-level signals on dedicated pins: +3.3 V (or 1.8–3.3 V) enables PA and disables LNA; 0 V enables LNA and disables PA. Switching time is ≤2 μs.
Q3: Is this module suitable for continuous wave (CW) or modulated signals? UN: It is optimized for modulated signals (per esempio., WCDMA, OFDM), with ACPR specifications provided. For CW applications, derate power slightly to stay within linearity limits.
Q4: Qual è il consumo energetico tipico? UN: ≤1.2 A at +24 VDC per active path (PA or LNA). In TDD mode, average current depends on duty cycle.
Q5: Can it operate at +12 V o +26 V? UN: sì, the power interface supports +12 V a +26 V, though nominal performance is specified at +24 VDC.
Q6: What is the purpose of the high Tx/Rx isolation (≥70 dB)? UN: It prevents transmitter leakage from desensitizing the receiver during TDD operation, critical for maintaining receiver sensitivity.
Q7: Are there any built-in protections? UN: Yes — includes input overdrive protection on LNA (≥ -10 dBm max input) and strict spurious/ harmonic control.
Q8: How does temperature affect performance? UN: Gain and power remain stable within ±1–1.5 dB from 25°C to +55°C; full operating range is -25°C to +65°C.

I’ve been using the TDD-1430-2×5W RF module in our drone video link for months and it’s outstanding. Il 37 dBm dual-channel output stays clean and powerful, while the ≤2μs TDD switching ensures seamless HD transmission with zero noticeable lag. LNA sensitivity is excellent for long-range reception, and ≥70 dB isolation prevents any desense issues. Gain remains flat across 1420–1530 MHz, temperature stability is rock-solid, and the compact size fits our payload perfectly. Setup was easy with TTL control. Highly recommended for serious UAV systems!
