2.4 and 5GHz WIFI Radio description There are two Wifi Radios in TG1672G and TG1662G (2.4GHz and 5GHz Radios), both models use a common pcb and housing where TG1662G is a stuffing option of TG1672G without MoCA 1.1. Both radios comply with the 802.11n protocol and support 3x3 MIMO. 2.4GHz Radio Digital interface is PCIe to the Puma6. A 40 MHz crystal provides the reference clock for the radio The CLR260 converts the transmit data to WIFI frequencies. On the receive side the WiFi data is converted back to digital. The CLR260 supports 802.11n 3x3 MIMO protocol. The transmit output of the CLR260 is filtered amplified by a discrete pre-amp and further amplified in the Skyworks SE2620T front end module. The SE2620T also contains a T/R switch that is controlled by the CLR260. The output of the SE2620T is filtered to ensure compliance to FCC and fed to an on board PCB antenna. On the receive side the signal is amplified in the SE2620T by the LNA and this signal is fed to the CLR260. Three separate WiFi chains each with its own pcb antenna provide the 3x3 MIMO. 5 GHz Radio Digital interface is PCIe to the Puma6. A 40 MHz crystal provides the reference clock for the radio The CLR260 converts the transmit data to WIFI frequencies. On the receive side the WiFi data is converted back to digital. The CLR260 supports 802.11n 3x3 MIMO protocol. The transmit output of the CLR260 is filtered and amplified in the Skyworks SE5012T front end module. The SE5012T also contains a T/R switch that is controlled by the CLR260. The output of the SE5012TT is filtered to ensure compliance to FCC and fed to an on board PCB antenna. On the receive side the signal is amplified in the SE5012T by the LNA and this signal is fed to the CLR260. Three separate WiFi chains each with its own pcb antenna provide the 3x3 MIMO

1. Following report presents the measurements of the optimized 1672 SR2 antennas. Antennas were slightly tuned to their required frequency. This involved minor dimensions changes of the antennas' layout. All measurements were made on assembled PCB and with the housing. Due to the large amount of data, S11, Coupling, Azimuth patterns (both polarizations) and Elevation patterns (both polarizations) are given for each antenna in typical frequency rather than its entire frequency band. 2.

Ant5000-Ant5002 10. Analysis and Conclusions a. All antennas are very well matched over their band. They minor layout adjustment especially in the 5G band. b. Gain of all antennas are similar to previous measurement (see 1672 _ Optimized SR1 Antenna Report_120807 report); Typical Gain of all antennas: ~(+)3.0 dBi. c. Minor differences in Radiation Patterns compare to previous measurement were recorded (probably due to measurements accuracy and manufacturing tolerances). d. In general there is good isolation between antennas. Coupling between 5G antennas is better than coupling between 2.4G antennas due to the relative wavelength. True HD Home Networking.
