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.

General description
this is a type of high frequency PCB built on PTFE 1.5mm substrate for the application
of 4 way divider. It's a 2 layer RF PCB board at 1.6 mm thick. It's OSP finish with green
Solder mask. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10
Boards are packed for shipment. 


Features and benefits
Stable electrical coefficient of dielectric constant.
RO4003C exhibit a stable dielectric constant over a broad frequency range. this makes
It an ideal substrate for broadband applications.
the dielectric constant (DK) is low and stable, so the signal transmission is good without
Delay.
Immersion gold has excellent surface planarity, particularly helpful for PCBs with BGA
Packages or even CSP mounted components to reduce failure rate during assembly and
Soldering.
UL, ISO certified PCB manufacturing factory.
Strict WIP inspection and monitoring as well as working instruction, 
Focus on low to medium volume production
Diversified shipping method
International approvals


Application
RF module, Power divider, Microstrip antenna, Trunk amplifier
