Usually connected to input of external low frequency CMOS synthesizer (Fujitsu MB87006A, Siemens PMB2307, or similar). 2 VCOON Control Logic “1” turns on power to VCO, and divider/prescalers. 3 VBATT Power VBATT connection for regulator. Normally connected to 3.3 V dc or battery. 4 VBASE Power Base connection to external regulator pass transistor (MMBT3906 or similar). 5 TANK– Input Connection for VCO tank circuit (LC network). 6 GND Power Substrate ground connection. 7 TANK+ Input Connection for VCO tank circuit (LC network). 8 RSSI Output Received Signal Strength Indicator output signal. 9 TXIF Input Accepts modulated transmit signal at 10.7 MHz IF. 10 VREG Power Regulated VCC for LO from external pass transistor. 11 RXON Control Logic “1” turns on power to LNA and receive mixer stages. 12 LIMIN Input Input to limiting amplifier. 13 IFAMPCOM Input Input signal common for limiting amplifier. 14 IFAMPOUT Output Output of first stage of IF amplifier. Normally connected through 10.7 MHz filter to Pin 12 (LIMIN). 15 IFAMPIN Input Input to first stage of IF amplifier. 16 VCCIF Power Local VCC connection for IF amp/limiter stages. 17 RXMIXOUT Output 10.7 MHz IF Output. Normally connected through 10.7 MHz filter to IF amplifier input (Pin 15). 18 LNAGND Power Local ground for LNA. 19 GND Power Substrate ground connection. 20 RFIN Input LNA Input. Normally driven single-ended from 50 Ω source impedance. 21 VCCLNA Power VCC for LNA. 22 GND Power Substrate ground connection. 23 LIMOUT Output 10.7 MHz limiter output. 24 PAGND Power Local ground for PA stage emitter. Degeneration may be added. 25 RFOUT Output Transmitted RF output signal at 0 dBm level. 26 VCCTX Power Local VCC connection for TX stages. 27 TXON Control Logic “1” turns on power to transmit mixer, buffers, and PA stages. 28 PREMOD Input Prescaler Modulus control (HIGH = divide-by-64; LOW = divide-by-65).
