NEC's NPN SILICON RF
TWIN TRANSISTOR
UPA895TD
FEATURES
• LOW VOLTAGE, LOW CURRENT OPERATION
• SMALL PACKAGE OUTLINE:
1.2 mm x 0.8 mm
• LOW HEIGHT PROFILE:
Just 0.50 mm high
• TWO LOW NOISE OSCILLATOR TRANSISTORS:
NE851
• IDEAL FOR 1-3 GHz OSCILLATORS
DESCRIPTION
NEC's UPA895TD contains two NE851 high frequency silicon
bipolar chips. The NE851 is an excellent oscillator chip, featur-
ing low 1/f noise and high immunity to pushing effects. NEC's
new ultra small TD package is ideal for all portable wireless
applications where reducing board space is a prime consider-
ation. Each transistor chip is independently mounted and
easily configured for oscillator/buffer amplifier and other
applications.
