Description
The MLS9204-01745 synthesizer design integrates a high performance buffered VCO, PLL circuit and discrete loop filter in a
surface mount package. The SMT packaging provides electrical
shielding, easy PCB assembly and repeatable performance. The
synthesizer is designed for use in PCS CDMA base stations and is
optimised for coverage of the PCS Rx band with 50 kHz step size
and low phase noise.
M/A-COM synthesizers are manufactured in an ISO 9001 certified facility, incorporating surface mount assembly and automated
electrical testing. This ensures consistent electrical performance
and quality over volume production quantities.
Electrical Specifications1, TA = +25°C, VCC = +5V, ∆∆F = 50 kHz, FR = 15 MHz
(unless otherwise stated)
1. All specification limits ar e indicated values and apply over F
