Communication

For communication area, KeyLink RF power amplifiers provide excellent performances for civil security, mobile communication fixed station such as CDMA, 4G, networks and IOT.

The microwave and RF amplifiers amplify power of the signal carrier, to realize long distance wireless transmission. The higher RF power amplifier's output power is the wider the coverage area is. Our RF power amplifiers give output power from 30w to 200w, with frequencies such as:

225-400M

890-960M

800-1000M

1710-1880M

1800-2000M

1930-1990M

1920-2170M

2110-2170M

2620-2690M

Also, customization is available.

KeyLink utilize all state of art GaN, LDMOS, MOSFET, GaAs FET and Bipolar RF device technologies, with key features as:

great linearity

distortion reduction technology

low heat radiation risk

long term stability

MCM and PCB are combined to balance cost and compactness. Functions such as forward detector, current monitor, temperature monitor, VSWR protection and over temp protection are available.

Allowed to be applied in modes such as LTE, CW, FM, AM, DCS, GSM, CDMA, and WCDMA etc.

All Keylink Microwave solid state power amplifiers are with long term warranty.
