Introduction

SKYA21050 is a high-linearity power amplifier featuring fully matched input/output and high gain. This compact 5×5 mm power amplifier is designed for Japanese market 760 MHz vehicle-to-vehicle and infrastructure communications based on the ARIB STD-T109 standard. The device integrates an active bias circuit to compensate for power amplifier performance variations due to temperature, voltage, and process changes, and incorporates an internal coupler for power monitoring.

Features

• AEC-Q100 Grade 3 (-40°C ~ +85°C) qualification in progress
• High gain: 35 dB (unconditionally stable)
• High linearity: Adjacent Channel Power (ACP) ≤ -39 dBm/100 kHz, POUT = +23.5 dBm (10 MHz signal bandwidth LTE modulated signal)
• RF input and output internally matched to 50 Ω
• Integrated active bias: performance temperature-compensated
• Integrated coupler for output power monitoring
• PA on/off function: 4.0 μs switching time
• Single supply voltage: 3.3 V
• Minimal external components
• Level 3 PPAP available for mass production
• Compact 5×5 mm, 28-pin package (MSL3, 260°C, compliant with JEDEC J-STD-020)

Applications

• Japan Intelligent Transport Systems 700 MHz power amplifier
• LTE cellular Band 13 power amplifier
• Active distributed antenna system
• Cellular repeater
• Driver amplifier
