TECHNICAL FAQ
01 PRODUCT FAMILY
Choose a CATV amplifier for high-linearity broadband cable paths, an LNA for weak-signal receiver inputs, a CATV VGA for analog level control, a digitally controlled VGA for stepped or processor-controlled gain, and an RF gain block for general-purpose broadband amplification.
02 KEY PARAMETERS
The main parameters are operating frequency, gain, noise figure, P1dB, OIP3, gain-control range or step size, supply voltage, current and package. Their priority depends on the signal level and application.
03 SELECTION INPUTS
Please provide the frequency range, input level, required gain or output level, noise-figure and linearity targets, gain-control method, supply voltage, package preference and end application.
Send your frequency range, gain, noise figure, linearity and gain-control requirements to the SANLAND engineering team.
