DC-to-Microwave, +5V Low-Noise Amplifier
______________________________________________________________Pin Description
PIN
NAME
FUNCTION
1
IN
Amplifier Input. Use a series blocking capacitor with less than 3Ω reactance at your lowest operating
frequency.
2
GND
Ground Connection. For optimum performance, provide a low-inductance connection to the ground
plane.
3
OUT
Amplifier Output. Use a series blocking capacitor with less than 3Ω reactance at your lowest operat-
ing frequency.
Supply Connection. Bypass directly at the package pin. The value of the bypass capacitor is deter-
4
VCC
mined by the lowest operating frequency and is typically the same as the blocking capacitor value.
For long VCC lines, additional bypassing may be necessary.
