Low-Band LNA Front-End Module (B26/B5/B18/B19, B8, B20, B12/13/17, B28A, B28B, and B29)

The SKYA25000 is an LNA diversity module used in cellular mobile devices. The module is typically placed close to the cellular diversity receiver antenna to enable improved system signal-to-noise ratio (SNR), improved user equipment (UE) sensitivity, and higher data throughput rates.

It is compatible with 3GPP GSM, WCDMA, and LTE standards and supports the following cellular bands: B26/B5/B18/B19, B8, B20, B12/13/B17, B28A, B28B, and B29.

The SKYA25000 is packaged in a small 4.0 x 3.0 x 0.7 mm (max), 24-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 -40 °C to +95 °C ambient.
