DESCRIPTION
The UPA838TF contains one NE688 and one NE687 NPN high
frequency silicon bipolar chip. NEC's new low profile TF
package is ideal for all portable wireless applications where
reducing component height is a prime consideration. Each
transistor chip is independently mounted and easily configured
for oscillator/buffer amplifier and other applications.
