Impedance Control Hybrid PCB RO4350b and Fr4 with Immersion Silver

1.1 General description

This is a type of mixed PCB built on 20mil RO4350B substrate and FR-4 combined for the
application of Wireless Range Extender. It's also an impedance controlled board. 50 ohm
single end impedance is controlled on top layer and bottom layer.It's 1.8 mm thick with 4
layers copper of 2oz weight, white silkscreen on blue solder mask and immersion silver on
pads. The base material is from Rogers Corp supplying single up PCB per panel. They're
fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 boards are packed
for shipment.

1.2 Features and benifits

A. RO4350B exhibits a stable dielectric constant over a broad frequency range. This makes
it an ideal substrate for broadband applications;
B. Good high temperature and low temperature resistance(-192ºC-260ºC);
C. Superior corrosion resistance;
D. SI performance improvement over the stack-ups with all FR4 board;
E. Quick CADCAM checking and free PCB quotation;
F. Professional and experienced engineers;
G. Competitive price.

1.3 Application

Antenna, Antenna combiner, Balanced amplifier, 3G antenna
