Product Description

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 called microwave.

Typical frequencies for wireless applications:

* Current mobile: 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: High Frequency PCB On 30 mil RO4350B With Double Layers

(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 PCB built on high frequency substrate with Tg 288°C for the application of Phone Signal Booster. It’s 0.8 mm thick, white silkscreen over green solder mask. All via’s are open to air. Pads are plated by immersion gold. The base material is used from Rogers RO4350B, entire board supplying 1 PCB up. They’re fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 panels are packed for shipment.
