Advance Information

Synthesizer Receiver

This document contains the information of a frequency

synthesized receiver prototype for FLEX roaming paging

platform. This FLEX paging receiver board is a high

performance RF/IF front–end for using in FLEX roaming

pager. This board employs Motorola’s high frequency

transistors MMBR941LT1, a M–ary FSK FM IF receiver

MC2800 as well as NPC’s phase lock loop SM5166AV as the

c o re. The whole module inc ludes a LNA, a

voltage–controlled oscillator, a frequency multiplier, a PLL, a

mixer and a FSK IF receiver.

Features:

4.3 mA @ VCC = 1.15 V,

0.08 mA @ VDD = 3.0 V
