The trace from Pin No. 29 to antenna connector on the OEM PCB must be maintained identical as the above
specification with SMA connector. Only trace designs approved with an original grant or through permissive change
can be used by an OEM, any changes are deemed as antenna type change and should be reviewed to ensure
compliance with the FCC and ISED requirements.
Verification must be conducted and the results shall not exceed below ranges to ensure identical antenna design
is applied to subsequent integration and end product production.
Impedance 50 ohm
Input power > 23dBm Average power
VSWR absolute max ≤ 10:1 (limit to avoid permanent damage)
VSWR recommended ≤ 2:1 (limit to fulfill all regulatory requirements)
6.3 Test procedures of verification
1. Set Transmission in the supported modulation mode from the device in engineering mode.
2. Verify RF power through conducted measurement at balanced impedance of 50ohms, the KDB 971168 D01
Power Meas License Digital System shall be used as the supplemental test methodology to adjust the proper
setting obtaining the measurement results.
3. Verify the Tx power in datasheet, and compliance test reports.
6.4 MIPI RFFE for Antenna Tuning
MIPI RFFE, is a dedicated control interface for the RF front-end subsystem. This interface allows antenna
designer to optimize antenna performance for different LTE bands. They can tune the antenna for different bands
by using a compliant MIPI RFFE switch. Currently the module only supports the Sony Switch (CXA4472GC-E).
The following signals are used for the MIPI interface.
RFFE_SCLK, RFFE_SDATA, RFFE_VDDIO_OUT
6.5 GPS Coexistence
Two pins are provided for GPS coexistence. AUX_ADC1 is used for GNSS coexistence indicator and
FLASH0_CS_N1 is used for GNSS SFN indication.
Other advanced GPS coexistence features will be available in a future firmware release.
7 APPLICATION PCB DESIGN
The Type 1SC modules have been designed to be compliant with a standard lead-free SMT process.
7.1 Solder Reflow
Recommended solder reflow profile:
