       Hittite 公司的HMC815LC5是GaAs MMIC I/Q 21 - 27 GHz上变换器,小信号变换增益12dB,边带抑制+20dB,输出IP3为+27dBm,主要用于点对点和点对多点无线电,军用雷达,EW和ELINT,卫星通信和传感器.本文介绍HMC815LC5主要特性, 方框图和应用电路图以及评估板PCB布局图与材料列表.

HMC815LC5: GaAs MMIC I/Q UPCONVERTER 21 - 27 GHz

The HMC815LC5 is a compact GaAs MMIC I/Q upconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 12 dB with +20 dB of sideband rejection. The HMC815LC5 utilizes a driver amplifier preceded by an I/Q mixer where the LO is driven by an active x2 multiplier. IF1 and IF2 mixer inputs are provided and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for fi ltering of the unwanted sideband. The HMC815LC5 is a much smaller alternative to hybrid style single sideband upconverter assemblies and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.

HMC815LC5主要特性:

High Conversion Gain: 12 dB

Sideband Rejection: 20 dB

2 LO to RF Isolation: 10 dB

Output IP3: +27 dBm

32 Lead 5x5mm SMT Package: 25mm2

HMC815LC5应用:

The HMC815LC5 is ideal for:

• Point-to-Point and Point-to-Multi-Point Radio

• Military Radar, EW & ELINT

• Satellite Communications

• Sensors
