DESCRIPTION
The UPA836TC contains one NE685 and one NE688 NPN
high frequency silicon bipolar chip. NEC's new ultra small TC
package is ideal for all portable wireless applications where
reducing board space is a prime consideration. Each transistor
chip is independently mounted and easily configured for oscil-
lator/buffer amplifier and other applications.
