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;
High frequency substrate + metal base etc.

PCB Case: Double Sided High Frequency PCB on
RO4003C 32mil (0.813mm)
(PCB's are custom-made products, the picture and parameters shown are just for
Reference)


General description
this is a type of high frequency PCB built on RO4003C for the application of multicoupler.
It's a 2 layer RF PCB board at 0.9 mm thick. It's HASL finish with solder mask and silkscreen
from Taiyo. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 boards
Are packed for shipment. 


Features and benefits
It shows excellent high frequency performance due to low dielectric tolerance and loss.
Stable electrical coefficient of dielectric constant.
Excellent dimensional stability.
Gold has high solderability, no stressing of circuit boards and less contamination of PCB
Surface.
High voltage test, Impedance control test, micro-section, solder-ability test, 
Thermal stress test, reliability test, insulation resistance test and ionic contamination test,
No MOQ, low cost for prototypes and samples. 
More than 15 years' experience
Delivery on time: >98%  


Application
LNA, VHF radio, Optoelectronic Transmitters, Tower Mounted Amplifier
