Description

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  3.0  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. A functional block diagram is shown in Figure 1.
