LMX9402
Frequency Synthesizer Module
General Description
The Frequency Synthesizer Module is a Low Temperature
Co-fired Ceramic (LTCC) RF module consisting of a high
performance frequency synthesizer, loop filter, and voltage
controlled oscillator (VCO). The frequency synthesizer is
fabricated using National’s ABiC BiCMOS process (f_T = 14
GHz). The loop filter and VCO are fabricated on National’s
Low Temperature Co-fired Ceramics.
The Frequency Synthesizer Module can be used for local
oscillator applications. Using a digital phase locked loop
technique, the on board frequency synthesizer can generate
a very stable, low noise local oscillator. Serial data is trans-
ferred into the module using a three wire interface. The loop
filter is designed for fast lock times and maximum attenua-
tion of reference spurs.
The module is available in a Ball Grid Array 560 mil X 560 mil
X 220 mil package.
