Sky5® Front-End Module for NR, LTE, WCDMA, and CDMA

The SKY58260-11 Front-End Module (FEM) is a fully matched, 79-pad surface mount (SMT) module developed for 5G / 4G / 3G / LTE / WCDMA / HSDPA / HSUPA applications. The FEM consists of PA blocks, input and output matching, a MIPI® standard digital control block, single-ended duplexers, antenna and band select switches, and low Noise amplifier (LNA) in a single 6.4 mm x 5.0 mm x 0.85 mm (Max.) package.

The SKY58260-11 is part of our Sky5® product portfolio.

The SKY58260-11 uses an enhanced architecture to cover multiple bands and meet the spectral linearity requirements of LTE QPSK, 16QAM, 64QAM, 256QAM modulations with up to 20 MHz bandwidth and up to 100 resource block allocations. Output power is controlled by varying the input power and VCC is adjusted using an ET modulator to maximize efficiency. Extremely low leakage current maximizes handset standby time.
