SEMICONDUCTOR TECHNICAL DATA
The RF Small Signal Line
The MRF9820T1 is a high performance GaAs AGC amplifier suitable for use
in low noise front end amplifier or downconverter applications. The device
contains two enhancement mode MESFETs connected in cascode to allow
access to both gates for gain control or injection of LO signals. This device is
well suited for low voltage, low current front–end applications such as paging,
cellular, GSM, DECT, and other portable wireless systems.
• Low Noise Figure: 1.5 dB @ 940 MHz, 1 mA
• Built In ESD Protection
• Does Not Require a Negative Supply Voltage
• RF Power Gain 16 dB @ 940 MHz, 1 mA
• High Third Order Intercept Point
• Industry Standard SOT–143 Surface Mount Package
• Order MRF9820T1 for Tape and Reel Packaging.
T1 Suffix = 3,000 Units per 8 mm, 7 inch Reel.
