Mid-Band LNA Front-End Module (B25, B3, B66, B7, and B41B)

The SKY13719-11 is an LNA diversity module used in cellular mobile devices. The module is typically placed close to the cellular diversity receiver antenna enabling improved system signal-to-noise ratio (SNR), improved user equipment (UE) sensitivity, and higher data throughout rates.

High-performance LNAs with five variable-gain modes are integrated in this device to enable compatibility for next-generation LNA-less LTE transceivers.

It is compatible with 3GPP GSM, WCDMA, and LTE standards and supports the following cellular bands: B25, B3, B66, B7, and B41B.

The SKY13719-11 is packaged in a small 4 x 2.7 x 0.7 mm, 22-lead surface mount package. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied. The part can operate over the temperature range of -30 °C to +85 °C.
