Customized Filter and standard Filter for Sub-1GHz equipment

Temwell establish bandpass Filters for Sub-1GHz design application. According to

standard using frequency band and bandwidth, Temwell support full Sub-1GHz band

in order to give IoT application and M2M system the best communication quality,

such as, 783MHz, 722.5MHz, 868MHz, 928 MHz, 433MHz and 450Mhz, etc.

During these frequency band, Temwell provide not only standard BW spec., but also

support at least 5 different BW spec item for your RF design, ex: 5MHz, 10MHz,

15MHz, 20MHz, 30MHz, 40MHz, 60MHz, 80MHz, 100MHz, 130MHz,etc.

A. Bandpass Filter type

Temwell RF Bandpass Helical Filter, including PIN type filter and Connector type filter,

has excellent customized technology, which is the worldwide Expert for your RF

application.

Pin type Helical Filter

Connector type Module Filter

B. Customized Service

We sustain Frequency change service (from 45MHz ~2600MHz) and Bandwidth change service

(1MHz ~100MHz) to you, which means we could build up your specific protection cover around

your specific RF signal.

Not mater what frequency with what bandwidth, Temwell could build it up by Bandpass Filter in

Pin type or Module type as your wish.
