Cellular & Wireless InfrastructureDriver and buffer amplification.

ISM, WLAN & WLLWideband amplification in wireless systems.

DBS, TVRO & Tuner ApplicationsCompact gain stages for receiver front ends.

GAIN BLOCK DESIGN FOCUS

Match gain, linearity, output power and current to the RF signal chain

Gain block selection depends on more than gain alone. OIP3, P1dB, noise figure, supply current and package size determine how each device fits into a driver or buffer stage.

WHAT TO COMPARE

Gain & FrequencyConfirm the required broadband gain over the target RF or IF range.

OIP3Higher OIP3 improves multi-tone and multi-carrier linearity.

P1dBIndicates available output power before compression.

Noise & CurrentBalance noise figure against current consumption and power budget.

PORTFOLIO OPTIONS

Low CurrentSG117 for current-sensitive broadband stages.

High LinearityAG41 for balanced linearity and driver power.

Higher GainAG50 for added gain and lower NF.

Medium PowerAG55 for higher P1dB and OIP3 requirements.
