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
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.
