Product Description
The RF2052 is a low power, high performance, wideband RF frequency conversion
chip with integrated local oscillator (LO) generation and RF mixer. The RF synthe-
sizer includes an integrated fractional-N phase locked loop with voltage controlled
oscillators (VCOs) and dividers to produce a low-phase noise LO signal with a very
fine frequency resolution. The buffered LO output drives the built-in RF mixer which
converts the signal into the required frequency band. The mixer bias current can be
programmed dependent on the required performance and available supply current.
The LO generation blocks have been designed to continuously cover the frequency
range from 300MHz to 2400MHz. The RF mixer is very broad band and operates
from 30MHz to 2500MHz at the input and output, enabling both up and down con-
version. An external crystal of between 10MHz and 52MHz or an external reference
source of between 10MHz and 104MHz can be used with the RF2052 to accom-
modate a variety of reference frequency options.
All on-chip registers are controlled through a simple three-wire serial interface. The
RF2052 is designed for 2.7V to 3.6V operation for compatibility with portable, bat-
tery powered devices. It is available in a plastic 32-pin, 5mmx5mm QFN package.
