SSS

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

2. Çeyrek: How is the TDD switching controlled? bir: 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.

3. Çeyrek: Is this module suitable for continuous wave (CW) or modulated signals? bir: It is optimized for modulated signals (örneğin, WCDMA, OFDM), with ACPR specifications provided. For CW applications, derate power slightly to stay within linearity limits.

4. Çeyrek: Tipik güç tüketimi nedir? bir: ≤1.2 A at +24 VDC per active path (PA or LNA). In TDD mode, average current depends on duty cycle.

S5: Can it operate at +12 V or +26 V? bir: Evet, the power interface supports +12 V'ye +26 V, though nominal performance is specified at +24 VDC.

S6: What is the purpose of the high Tx/Rx isolation (≥70 dB)? bir: It prevents transmitter leakage from desensitizing the receiver during TDD operation, critical for maintaining receiver sensitivity.

S7: Are there any built-in protections? bir: Yes — includes input overdrive protection on LNA (≥ -10 dBm max input) and strict spurious/ harmonic control.

S8: How does temperature affect performance? bir: 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.
