Hot-selling and scarce SKY77709-12 Power Amplifier Module for LTE FDD Band VII QFN spot stock

Product Descriptions

The SKY77709 Power Amplifier Module (PAM) is a fully matched, surface mount module developed for  LTE / EUTRAN applications. This small and efficient module packs full coverage of LTE FDD Band VII  into a single compact package. The SKY77709 meets the stringent spectral linearity requirements of  LTE modulation with QPSK / 16QAM modulations from 1.4 MHz to 20 MHz bandwidth and full or  partial resource block allocations with high power added efficiency.

The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active  circuitry in the module, including the PA, input, and interstage matching. Output match is realized offchip within the module package to optimize efficiency and power performance into a 50 Ω load. The  SKY77709 is manufactured with Skyworks’ BiFET process which provides for all positive voltage DC  supply operation while maintaining high efficiency and good linearity. Primary bias is supplied via the  VCC1 and VCC2 pads directly from battery output in the 3.2 to 4.2 volt range. Power-down is  accomplished by setting a logic low level on the VEN pad. No external supply side switch is needed as  typical “off” leakage is a few microamperes with full primary voltage supplied from the battery. The  VMODE0 and VMODE1 pads are used to switch between high, medium and low power modes to  reduce current consumption and gain in the back-off conditions.
