Quad-Band Power Ampifier Module for FDD/TDD LTE (Tx Bands 7, 38, 40, 41)

The SKY77807 Quad-Band Power Amplifier Module (PAM) is a fully matched, 24-pad surface mount module developed for 4G LTE applications. The PAM consists of PA blocks, input and output matching, and a MIPI standard logic control block for multiple power control levels, output input switch control in a single 4.0 mm x 3.0 mm x 1.0 (Max.) mm package.

The SKY77807 uses an enhanced architecture to cover multiple bands and meet the spectral linearity requirements of LTE QPSK and 16QAM 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 or DCDC converter to maximize efficiency for each power level. Extremely low leakage current maximizes handset standby time.
