TDD 2*2W Dual Channel Digital Linear RF Power Amplifier 1420～1530M MIMO PA
Performance advantages
Extremely small size, dual-channel power amplifier (MIMO-PA), high linearity, extremely high reliability, no damage to the power amplifier even during open circuit or short circuit.
Specifications
Model number: HCTD-4055-2
Product name: TDD 2*2W Dual Channel Digital Linear RF Power Amplifier 1420～1530M MIMO PA
High linearity
Number of channels: 2 channels, symmetrical on both left and right sides.
Transmission Power: Nominal 2W for 2 channels, typical value 2-3W*2 . This enables longer transmission distances and more stable wireless transmission.
Frequency range: 1420~1530MHz or other frequencies
Gain: ≥12dB± 0.5 dB (TX mode)
Shoulder ratio: ≥25~30dB (at 8MHz bandwidth, DVB-T, 2/8K mode modulation signal, Deviation from the center frequency 4.3MHz)
Third order intermodulation: ≤-30~36dB@Pout=33dBm/ ≤-20~30dB@36dBm
ACPR: ≤-30~-36dB@Pout=33dBm/ ≤-20~30dB@36dBm
Harmonic suppression: ≤-30dBc
Output VSWR: ≤1.5 (load 50Ω)
Relative group delay: ≤20ns
RF switch switching time: turn on time≤1us / switch off time ≤0.2us
Power amplifier transmit-receive isolation degree: ≥45dB
Receive gain: 9± 2 dB* 2 or 2dB ± 0.5dB* 2 ( RX mode, the maximum gain of the low-noise amplifier can be set and changed according to the requirements up to 20dB).
Control mode: TTL 0/1.8～5V level (Or, automatic detection of the input power can be used to achieve automatic transmission and reception. However, the transmission delay will be slightly increased, but it can still be used normally. EN high level(1.5~5.5V): Power amplifier is in transmitting mode,but receiving is off. EN low level (0~1.0V) : Receiving status, but transmitting is off (power amplifier static current is less than 0.17A with low-noise amplifier )
Working temperature: -25~+85℃
Temperature protection: If the module temperature reaches 105 ± 5 degrees, the transmission will be automatically shut down and only reception will be enabled.
Supply voltage: 12V(10 - 16V ), the higher the voltage, the higher the output performance)
