RF Front End (LNA + PA)

This Product Selection Guide contains information to help select products in the RF Front End (LNA + PA) category on DigiKey.com

Products in this family are integrated circuits that integrate one or more of the functions commonly found in the portion of a radio frequency (RF) signal chain that is connected to the system’s antenna, such as a low-noise amplifier (LNA) and programmable amplifier (P A). The actual functionality incorporated into any given device varies, with devices targeting relatively narrow applications typically integrating a larger portion of the requisite signal chain than those intended to be more flexible in their application.


RF Type: Indicates the general application space or communications standard for which a device is intended for use.

Frequency: The frequency or frequencies this product is designed to be compatible.

Features: Identifies important product attributes that are intstrumental in finding a suitable selection.

Package / Case: The protective case on an electronic component which allows for easy handling, installation, and protects the device. This is what we determined is the closest industry standard to the supplier device package. Typically, it is best to use the actual dimensions from the datasheet rather than to go by this terminology when designing your circuit.

Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
