часта задаюць пытанні

Q1: What does “2× 5W” mean in the model name? А: It indicates dual transmit capability with up to 5W (37 дБм) output power per channel, supporting 2T2R (dual transmit, dual receive) configurations.

Q2: How is the TDD switching controlled? А: 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? А: It is optimized for modulated signals (напр., WCDMA, OFDM), with ACPR specifications provided. For CW applications, derate power slightly to stay within linearity limits.

Q4: Што такое тыповае спажыванне электраэнергіі? А: ≤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 або +26 V? А: ды, the power interface supports +12 V да +26 V, though nominal performance is specified at +24 VDC.

Q6: What is the purpose of the high Tx/Rx isolation (≥70 dB)? А: It prevents transmitter leakage from desensitizing the receiver during TDD operation, critical for maintaining receiver sensitivity.

Q7: Are there any built-in protections? А: Yes — includes input overdrive protection on LNA (≥ -10 dBm max input) and strict spurious/ harmonic control.

Q8: How does temperature affect performance? А: 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.
