SKY67105-306LF数据手册RF/IF射频/中频RFID的射频放大器规格书PDF

描述 Description

Please note: SKY67105-306LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY67179-306LF

The SKY67105-306LF is a GaAs pHEMT and HBT two-stage, LowNoise Amplifier (LNA) with active bias and high linearity performance. The pHEMT front end of the device provides an ultra-low Noise Figure (NF) while the HBT output stage provides high gain, linearity, and efficiency.

The SKY67105-306LF operates in the frequency range of 0.6 to 1.1 GHz. For higher frequency operation, the pin and layout compatible SKY67106-306LF should be used.

The SKY67105-306LF operates in the frequency range of 0.6 to 1.1 GHz and the associated evaluation board designs are optimized for operation in the 0.75 – 0.95 GHz band. For higher frequency operation, the pin and layout compatible SKY67106-306LF is available as well. The LNA is manufactured in a compact, 4 x 4 mm, 8-pin Quad Flat No-Lead (QFN) package and is categorized as Skyworks Green.

特性 Features

• Ultra-low NF: 0.69 dB @ 850 MHz
• High gain: 37 dB @ 850 MHz
• +4 or +5 V operation for improved efficiency
• Stage 1 adjustable gain and current
• Wideband performance, useable to 1.1 GHz
• Small, QFN (16-pin, 4 x 4 mm) Pb-free package (MSL1, 260 °C per JEDEC J-STD-020)

简介

SKY67105-306LF属于RF/IF射频/中频RFID的射频放大器。由制造生产的SKY67105-306LF射频放大器在射频应用中，射频放大器产品可用于信号增益和缓冲。这些产品与通用运算放大器的不同之处在于，它们通常适用于更高的频率，更倾向于提供不可调节的固定增益，并且输入或输出阻抗值符合常用传输线特性阻抗。
