Description
The SKY77830 Dual-Band Power Amplifier Module (PAM) is a fully matched, 16-pad surface mount
module developed for 4G LTE applications. The PAM consists of PA blocks, input and output matching
circuitry to 50 Ω, a directional coupler, a Tx-Rx switch, a MIPI^® standard logic control block for
multiple power control levels and switch control in a single 2.5 mm x 2.9 mm x 0.8 mm package.
The SKY77830 enhanced architecture covers multiple bands and meets the spectral linearity
requirements of LTE QPSK and 16QAM modulations with up to 20 MHz bandwidth and up to 100
resource block allocations. Varying the input power controls the output power, and VCC1 / VCC2 is
adjusted using a DCDC converter to maximize efficiency for each power level. Extremely low leakage
current maximizes handset standby time.
