Brief Introduction
Just as its name implies, high frequency is that the frequency is relatively high, generally refers
to the frequency of >=300 MHz (i.e. Wave length <=1m), that is, the usual radio frequency
Band. the electromagnetic wave of frequency >=1GHz is named microwave.
Typical frequencies for wireless applications:
* Current: 0.9GHz - 2GHz
* 3G systems: 2.5GHz
* Bluetooth: 2.5GHz
* GPS: 12.6GHz
* LMDS: 24GHz and 40GHz
* Automotive: 77GHz
Market: RFID, Wireless communications, base station and antenna, amplifier, military products,
Consumer electronics.  
High frequency printed circuit board or microwave PCB refers to the printed circuit board made
on the high frequency (microwave) substrate copper clad plate. the common types are: Double
-sided board, multilayer board and mixed structure.
Mixed structure includes high performance special substrate, PP sheet + ordinary performance
Board and PP sheet mixed pressing board; high frequency substrate + ordinary FR4 substrate;
Frequency substrate + metal base etc.



PCB Case: 1.6mm High Frequency PCB on RO4350B
with Black Text on Substrate
(Printed circuit boards are custom-made products, the picture and parameters shown are
Just for reference)


General description
this is a type of double sided RF PCB built on RO4350B substrate with Tg 280C for the
of WiFi Repeater. It's 1.60 mm thick without solder mask; Black silkscreen is directly on
the substrate and HASL is on pads for soldering. the base material is used from Rogers
Corp., entire board supplying 1 up. They're fabricated per IPC 6012 Class 2 using supplied
Gerber data. Each 25 boards are packed for shipment. 

Features and benefits
RO4350B exhibits a stable dielectric constant over a broad frequency range. this makes
It an ideal substrate for broadband applications;
Reducing signal loss in high frequency application meets the development needs of
Technology;
