General Description
The PMB 2347 is a RF/IF double PLL
frequency synthesizer implemented in
Infineon’ high speed BiCMOS technol-
ogy B6HFC. The device contains two
PLLs with integrated prescalers espe-
cially designed for use in battery pow-
ered radio equipment and mobile
telephones. Primary applications are
single- and dual-band digital cellular
systems e.g. GSM, PCN (DCS 1800)
and PCS systems.
