背后版本拍个照看看？我前两周刚查完，有换功放的情况，原本是QPF4588，换成KCT8548HE，硬件版本依旧是1.0，
QPF4588参数如下：
5150 – 5925 MHz
POUT = +16dBm MCS11 HE80 -47dB Dynamic EVM
POUT = +18dBm MCS11 HE80 -43dB Dynamic EVM
POUT = +23dBm MCS9 VHT80 -35dB Dynamic EVM
POUT = +24dBm MCS7 HT20/40 -30dB Dynamic EVM
POUT = +26dBm MCS0 HT20 Spectral Mask Compliance
Optimized for +5 V Operation
33 dB Tx Gain
2 dB Noise Figure
16 dB Rx Gain & 7 dB Bypass Loss
30 dB 2.4 GHz Rejection on Rx Path
Integrated RF Power Detector Coupler as well as DC Power Detector
KCT8548HE的参数如下：
Integrated high performance 5GHz PA, LNA with bypass and T/R switch
Fully-matched input and output
Integrated power detector
Transmit gain: 30.5dB at 5V
Receive gain: 16dB at 5V
Noise figure: 1.9dB at 5V
Output power:
+16.5dBm @ -43dB HE160, MCS11 DEVM, 5V
+21dBm @ -40dB HE160, MCS11 DEVM, 5V
+23dBm @ -35dB VHT80, MCS9 DEVM, 5V
+24dBm @ -30dB HT20, MCS7 DEVM, 5V
ESD protection circuitry on all PINs
Minimal external components required
Small package: QFN-24L, 3mm x 5mm x0.75mm (MSL3, 260 oC per JEDEC J-STD-020)
RoHS and REACH compliant |
