負責(zé)四個千兆網(wǎng)口的交換芯片MT7531A：

連接兩個2.5G網(wǎng)口的2.5G PHY芯片：RTL8211B。

現(xiàn)在看無線射頻電路。

2.4G無線RF芯片型號是MT7976GN：

有四顆獨立的FEM芯片，型號是KCT8239SD，上海康希通信科技公司的產(chǎn)品。

KCT8239SD參數(shù)：
Integrated high performance 2.4GHz PA, LNA with bypass, and T/R switch
Fully-matched input and output
Integrated Power Detector
Transmit gain: 30.0dB at 5V
Receive gain: 15.5dB at 5V
Noise figure: 2.5dB at 5V
Output power:
+20.5dBm @ -43dB DEVM, HE40/MCS11,5V
+21.5dBm @ -40dB DEVM, HE40/MCS11,5V
+23.5dBm @ -35dB DEVM, VHT40/MCS9,5V
+24.5dBm @ -30dB DEVM, HT20/MCS7,5V
ESD protection circuitry on all PINs
Minimal External Components Required
Small package: QFN-16L, 3mm × 3mm × 0.75mm (MSL3, 260 oC per JEDEC J-STD-020)
RoHS and REACH Compliant

接著另一側(cè)的是5G無線RF芯片：

5G也外置了四顆獨立的FEM芯片，型號是KCT8539HE-1：

KCT8539HE-1的參數(shù)：
Integrated 802.11ax 5GHz PA, LNA with bypass and T/R switch
Fully-matched input and output
Integrated power detector
Transmit gain: 32dB at 5V
Receive gain: 14.5dB at 5V
Noise Figure: 2.8dB at 5V
Output power:
+19.5dBm @-43dB DEVM, HE160//MCS11, 5V
+21dBm @-40dB DEVM, HE160//MCS11, 5V
+22.5dBm @-35dB DEVM, VHT80/MCS9, 5V
+23.5dBm @-30dB DEVM, HT20/MCS7, 5V
Integrated 2.4GHz Notch Filter
ESD protection circuitry on all PINs
Minimal external components required
Small package: MIS16-pin, 3mm

KCT8539HE-1相對KCT8539HE來說是增強版。

MT7976GN和MT7976AN都是單頻4T4R的無線射頻芯片。
