Low-Noise Amplifier/Mixer
The HFA3600 is a silicon Low-Noise Amplifier with high
performance characteristics allowing the design of very
sensitive, wide dynamic-range 900MHz receivers with
minimal external components.
The LNA, Mixer RF, and LO inputs are internally matched to
50Ω. The Mixer IF output is open collector allowing flexibility
in choosing the IF output impedance, with 1000Ω operation
fully characterized. The mixer performance is optimized for
low LO drive (-3dBm) applications.
Power consumption is kept to a minimum, making the device
ideal for battery-powered hand-held communication
equipment. An integrated power-down feature maximizes
battery life and eliminates the need for external shut down
circuitry. Although fully characterized under 5V single supply,
the HFA3600 is operable down to 4V with slight performance
differences.
The HFA3600 is part of a complete solution including
application circuit schematics, S-parameters, noise figure,
third-order intercept characterization data and PC board
artwork. Evaluation boards are also available through local
Intersil Sales offices.
