Description
The TARF2304 is a complete low power consumption, double balanced active mixer.
It is designed for narrow or wide bandwidth commercial and industrial applications
having RF inputs up to 2 GHz. The TARF2304 is particularly well suited for
applications that require load-insensitive conversion and good spurious signal
suppression with minimum LO and bias power consumption.
The TARF series of gilbert multiplier-based frequency converters is fabricated
using Tachyonics's TAHB09 Silicon-Germanium HBT process.
Features
RF-IF Conversion Gain From 0.052 GHz
Low Power Dissipation : 50 mW at VCC = 5 V Typical
Single Polarity Bias Supply : VCC = 4 to 8 V
Load-insensitive Performance
Conversion Gain Flat Over Temperature
Low Cost Plastic Surface Mount Package
Applications
Frequency Down Conversion, Modulation, Demodulation and Phase Detection.
Fiber-Optics, GPS Satellite Navigation, Mobile Radio.
Battery Powered Communications Receivers.
