SKY12235-11数据手册RF/IF射频/中频RFID的衰减器规格书PDF

描述 Description

Please note: SKY12235-11 is being discontinued and is not recommended for new designs. The suggested replacement is SKY12239-11

The SKY12235-11 is a voltage-controlled variable attenuator fromSkyworks series of high 3rd Order Input Intercept Point (IIP3)components. The device has been designed to operate over the1.4 to 2.4 GHz frequency band, but is specifically optimized foruse as a wide dynamic range, low distortion attenuator, centeredat 1.9 GHz.

The SKY12235-11 provides monotonic attenuation performanceover its entire control voltage range. This attenuator is comprisedof a pair of matched PIN diodes that terminate two ports of itsinternal 90-degree hybrid coupler. The diodes are biased using anexternal control voltage signal. The attenuator requires noexternal components. It operates with a control voltage range of 0to 5 V and a 1.7 mA typical control current at maximumattenuation.

特性 Features

• 1.4 to 2.4 GHz broadband operating range
• Maximum attenuation level: 36 dB
• Control voltage range: 0 to 5 V
• High IIP3: +61 dBm
• Low current consumption: <2 mA @ maximum attenuation
• Small, MCM (8-pin, 4.9 x 3.2 mm) package (MSL1, 260°C per JEDEC J-STD-020)

简介

SKY12235-11属于RF/IF射频/中频RFID的衰减器。由制造生产的SKY12235-11衰减器衰减器旨在降低信号功率，同时尽量减少其对波形的影响。衰减值的范围为 0 dB 至 69 dB，频率范围为 0 至 86 GHz。
