描述 Description

Please note: SKY65338-21 is being discontinued and is not recommended for new designs. Skyworks SKY65338-21 is a high-efficiency Front-End Module(FEM) that incorporates a transmit and receive path, and anantenna transmit/receive (T/R) switch.

The transmit path consists of a high efficiency Power Amplifier(PA) followed by an harmonic filter for rejection of harmonicfrequencies.

The PA is implemented using Skyworks high reliabilityHeterojunction Bipolar Transistor (HBT) process and is Class ABbiased to provide maximum efficiency with a low spurious output.

A high linearity and high isolation Single-Pole Double-Throw(SPDT) switch is used at the common antenna interface betweenthe transmit and receive paths. The receive path is a low insertionloss through-path with input and output ports internally matchedto 50 Ω.

The device is mounted in a 12-pin, 8 x 8 mm Multi-Chip Module(MCM) Surface-Mounted Technology (SMT) package, whichallows for a highly manufacturable low-cost solution.

特性 Features

• Transmit output power > +25 dBm
• High gain in transmit path: 32 dB
• High transmit/receive isolation > 30 dB
• Internal RF match and bias circuits
• All RF ports internally DC blocked
• Single DC supply = +3.6 V
• Small footprint, MCM (12-pin, 8 x 8 mm) SMT package (MSL3, 260 °C per JEDEC J-STD-020)

应用 Application

• Connected Homes

简介

SKY65338-21属于RF/IF射频/中频RFID的射频前端（LNA+PA）。由制造生产的SKY65338-21射频前端（LNA + PA）本系列中的产品是各种集成电路，其中集成了射频 (RF) 信号链连接到系统天线的部分中常见的一种或多种功能，如低噪声放大器 (LNA) 和可编程放大器 (PA)。任何给定器件所含的实际功能各不相同，相比旨在提供更高应用灵活性的器件，针对相对较窄应用的器件通常集成更大一部分必要的信号链。
