DESCRIPTION
The NE687 series of NPN epitaxial silicon transistors are
designed for low cost, low noise applications. Excellent perfor-
mance at low voltage/low current makes this series an ideal
choice for portable wireless applications at 1.6, 1.9 and 2.4
GHz. The NE687 die is available in six different low cost plastic
surface mount package styles.
ELECTRICAL CHARACTERISTICS (TA = 25°C)
•LOW NOISE: 1.3 dB AT 2.0 GHz
•LOW VOLTAGE OPERATION
•EASY TO MATCH
•HIGH GAIN BANDWIDTH PRODUCT: fT of 13 GHz
•AVAILABLE IN SIX LOW COST PLASTIC SURFACE
MOUNT PACKAGE STYLES
Notes:
1. Precaution: Devices are ESD sensitive. Use proper handling procedures.
2. Electronic Industrial Association of Japan.
California Eastern Laboratories
3. Pulsed measurement, PW ≤ 350 µs, duty cycle ≤ 2%.
4. The emitter terminal should be connected to the ground terminal
of the 3 terminal capacitance bridge.
