SKY65185 1.7 – 2.7 GHz Dual-Channel, Variable Gain Amplifier Front-End Module
SKYWORKS SKY65185 is a high dynamic range receive Variable Gain Amplifier (VGA) Front-End Module (FEM) for 3G and LTE infrastructures and other applications that operate in the 1.7 to 2.7 GHz band. The SKY65185 contains two Digital Step Attenuators (DSAs) and two Power Amplifiers (PAs). The DSA is a 6-bit attenuator with an 0.5 dB step size that provides 31.5 dB of total attenuation. The DSA is controlled using an on-chip Serial Peripheral Interface (SPI) logic circuit.
