SKY65388-11中文资料695 to 866 MHz Variable Gain Amplifier数据手册Skyworks规格书

描述 Description

Please note: SKY65388-11 is being discontinued and is not recommended for new designs.

The SKY65388-11 is a high linearity, Variable Gain Amplifier (VGA)module. The device includes an input amplifier driver, a VariableVoltage Attenuator (VVA), and an output Power Amplifier (PA). Thetwo amplifiers and voltage attenuator are optimized for superiorACLR performance with WCDMA signals.

The high linearity (high OP1dB, OIP3, and ACLR) and highefficiency of this device make it ideal for use at the final stage (orclose to the final stage) of a WCDMA transmit chain.

The output of the first PA (PA1) is matched to the input of the VVA.The output of the VVA is matched to the input of the second PA(PA2). The RF_IN and RF_OUT signals (pins 1 and 8, respectively)are both internally matched, including DC blocking capacitors.

The SKY65388-11 VGA uses low-cost Surface Mount Technology(SMT) in the form of a compact, 8 x 8 mm 12-pin Multi-ChipModule (MCM), which allows for a highly manufacturable low-costsolution.

特性 Features

• Frequency range: 695 to 866 MHz
• Attenuation range: > 30 dB
• ACLR < –68 dBc for POUT = +8 dBm
• Small MCM (12-pin, 8.385 x 8.385 mm) SMT package (MSL3, 260°C per JEDEC J-STD-020)

简介

SKY65388-11属于RF/IF射频/中频RFID的射频放大器。由制造生产的SKY65388-11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。
