개요

The TDD-1430-2×5W is an integrated RF front-end module optimized for TDD-based systems operating in the 1.42–1.53 GHz band (commonly used in UAV/drone video and telemetry links, private LTE/5G bands, industrial wireless networks, and point-to-point data transmission). It features independent PA and LNA paths with fast TDD switching controlled by TTL-level signals, enabling seamless transmit/receive operation. The module supports dual-channel (2×5W) transmission capability while maintaining excellent linearity, low spurious emissions, and stable performance across temperature variations (-25°C ~ +65°C). With compact dimensions (69 × 50 × 11.5 mm), 효율적인 +24 VDC power supply, and high port isolation (≥70 dB), 규모가 큰 까다로운 환경에 맞게 설계되었습니다., 전력 효율성, RF 성능이 중요합니다.

자주하는 질문

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

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

Q4: 일반적인 전력 소비량은 얼마입니까?? 에이: ≤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 또는 +26 V? 에이: 예, the power interface supports +12 V ~ +26 V, though nominal performance is specified at +24 VDC.

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

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

Q8: How does temperature affect performance? 에이: 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.
