LMX9301
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 IV BiCMOS process (f_T e
14 GHz) The loop filter and VCO are fabricated with Nation-
al’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 an 18-pin 500 mil c 500 mil c
125 mil (refer to dwg) package
