SKY68040-11

Multi-Mode, Multi-Band Power Amplifier Module for Cat M1/1/NTN and WCDMA HSDPA/HSUPA/ HSPA+ (Bands 1,2,4,5,8) and CDMA (Band Classes 0,1,6,15)

The SKY68040-11 is a multi-band Power Amplifier Module (PAM) supporting LTE Cat-M1, Cat1 IOT (optimized to support up to 6RB) and 5G IOT NTN Non- Terrestrial-Networks transceiver.

The SKY68040-11 meets stringent spectral linearity requirements for WCDMA, HSDPA, HSUPA, HSPA+ transmission with high power-added efficiency.

The module integrates a LTE multi-band radio operating in lowband (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 28, 71, 85), mid-band (1, 2, 3, 4, 24,25, 39, 66, 70) frequencies and NTN L-Band (B24, n255) + S-Band (n256), including broadband PAs with bias/ gain controller. A directional coupler integrated into the module eliminates the need for any external coupler.

The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC contains onboard bias circuitry, as well as input and interstage matching circuits. Output match into a 50-ohm load is realized off-chip within the module package to optimize efficiency and power performance.

The SKY68040-11 PAM is manufactured with Skyworks InGaP GaAs Heterojunction Bipolar Transistor (HBT) process which provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. No VREF voltage is required. Power down is accomplished by setting the voltage on VENHB and VENLB to zero volts. No external supply side switch is needed as typical “off” leakage is a few microamperes with full primary voltage supplied from the battery.
