PIN NAME

INTERFACE

8
VHF input
VHF-RF input. Normally, ground pin 7 to AC
using a capacitor and input to pin 8.
9
10
UHF input
UHF-RF input.
Either apply balanced input to pins 9 and 10
or ground pin 10 to AC and input to pin 9.
11
REG
Regulator output.
12
13
14
15
UHF oscillator
UHF oscillator.
Pin 12 uses both as band switch. Connecting
pin 12 to VCC via 22k sets to UHF ;
connecting pin 12 to GND sets to VHF. To
use VHF SW voltage open rather than GND,
connect a resistor of around 10k.
Changing capacitor of 6pF connected to pins
12 and 15 of test circuit 2 varies the
oscillation frequency range. Be careful not to
set the constant too large, because abnormal
oscillation may occur.

641mW for TA1281F (F-type), 543mW for TA1281FA (FA-type), 568mW for TA1281FN (FN-type).
When using the device at above Ta=25°C, decrease the power dissipation F-type by 5.2mW, FA-type by
4.4mW and FN-type by 4.6mW for each increase of 1°C.
