CMT2300A-EQR from HopeRF Micro electronics, in a QFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RFIP input RF signal input positive terminal for low-noise amplifier receiver supporting frequency range 127 to 1020 MHz.
2 RFIN input RF signal input negative terminal for low-noise amplifier receiver supporting frequency range 127 to 1020 MHz.
3 PA output Power amplifier RF output providing transmit capability with adjustable output power from -20 dBm to +20 dBm in 1 dB steps.
4 AVDD power_in Analog power supply voltage input, operating voltage range 1.8 V to 3.6 V.
5 AGND power_in Analog ground reference connection.
6 DGND power_in Digital ground reference connection.
7 DVDD power_in Digital power supply voltage input, operating voltage range 1.8 V to 3.6 V.
8 GPIO3 bidirectional Configurable general-purpose I/O pin supporting clock output (CLKO), demodulated output (DOUT), modulation input (DIN), or data rate clock (DCLK) in TX/RX modes.
9 SCLK input SPI serial clock input with maximum frequency 5 MHz; data is transferred on clock falling edge.
10 SDIO bidirectional SPI bidirectional serial data line for register and FIFO access; input high threshold ≥0.8 VDD, input low threshold ≤0.2 VDD.
