描述 Description

Please note: SKY12407-321LF is being discontinued and is not recommended for new designs.

The SKY12407-321LF is a GaAs pHEMT two-bit attenuator I/C.The device is provided in a 3 x 3 mm 12-pin Quad Flat No-Lead(QFN) package.

The SKY12407-321LF is particularly suited for 100 Ω differentialsystems for which high attenuation accuracy, low insertion loss,and low intermodulation products are required.

The attenuator’s differential input and output impedance is100 Ω. The device is controlled by two positive DC voltage controlpins. The differential attenuator paths are controlled together andcan be in either an insertion loss or a 12 dB attenuation state. In adifferential system, the attenuator presents a 100 Ω impedance,but can be used as two single-ended attenuators, each with a50 Ω impedance.

特性 Features

• Dual, positive voltage operation: 0/1.8-5.0 V
• High bit accuracy: ±0.3 dB @ 200 MHz
• Low insertion loss: 0.3 dB @ 200 MHz
• Absorptive in 100 Ω differential systems
• Small, QFN (12-pin, 3 x 3 mm) package (MSL1, 260 °C per JEDEC J-STD-020)

简介

SKY12407-321LF属于RF/IF射频/中频RFID的衰减器。由Skyworks制造生产的SKY12407-321LF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。
