GENERAL PURPOSE AMPLIFIER
• General Purpose Broadband Gain Blocks
• IF or RF Buffer Amplifiers
• Driver Stage for Power Amplifiers
• Final PA for Low Power Applications
• Portable Battery Powered Equipment
• Broadband Test Equipment
The RF2308 is a general purpose, low cost RF amplifier
IC. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as an easily-cas-
cadable 50
Ω gain block. Applications include IF and RF
amplification in wireless voice and data communication
products operating in frequency bands up to 4000MHz.
The device is self-contained with 50
Ω input and output
impedances and requires only two external DC biasing
elements to operate as specified.
• DC to 4000MHz Operation
• Internally matched Input and Output
• 12dB Small Signal Gain
• 5dB Noise Figure
• 20mW Linear Output Power
• Single Positive Power Supply
