The PMB 2240, 2245, 2247 family are single-chip transmitters which include a prescaler for the RF-oscillator signal and a fixed PLL for the IF-oscillator signal. The transmitter family is designed for use in combination with the single-chip receiver family PMB 2405, 2407 and the PLL PMB 2307 for mobile telephones according to the GSM, PCN and PCS standards and other vector modulated digital systems. It is fabricated using Siemens B6HF silicon process.
