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 |
