Introduction

The SKY12239-11 is a voltage-controlled variable attenuator belonging to a family of broadband, flat attenuation, high IIP3 components. The device is designed to operate in the 10 MHz to 1.5 GHz frequency band, specifically optimized for use as a wide dynamic range, low distortion attenuator. It provides monotonic attenuation performance across the entire control voltage range. The attenuator consists of four matched PIN diodes biased via an external control voltage signal, requiring no external components. Its operating control voltage range is 1 to 5 V, with a typical control current of 2 mA at maximum attenuation.

Features

• Wideband operation: 10 MHz to 1.5 GHz
• Low insertion loss: 2.5 dB @ 700 MHz
• Maximum attenuation: 40 dB @ 700 MHz
• Control voltage range: 1 to 5 V
• High IIP3: +50 dBm
• Low current consumption: < 2 mA @ maximum attenuation
• Compact MCM package (8-pin, 3.8 × 3.8 × 1 mm) (MSL3, 260 °C, JEDEC J-STD-020 compliant)

Applications

• Automatic power level/gain control circuits
• General-purpose wireless systems
