FN1345.6
High-Frequency NPN Transistor Array For
Low-Power Applications at Frequencies
Up to 1.5GHz
The CA3227 consists of five general purpose silicon NPN
transistors on a common monolithic substrate. Each of the
transistors exhibits a value of f
T
in excess of 3GHz, making
them useful from DC to 1.5GHz. The monolithic construction
of these devices provides close electrical and thermal
matching of the five transistors.
Features
• Gain-Bandwidth Product (f
T
) . . . . . . . . . . . . . . . . . >3GHz
• Five Transistors on a Common Substrate
Applications
• VHF Amplifiers
• VHF Mixers
• Multifunction Combinations - RF/Mixer/Oscillator
• IF Converter
• IF Amplifiers

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. The collector of each transistor of these devices is isolated from the substrate by an integral diode. The substrate (Terminal 5) must be connected
to the most negative point in the external circuit to maintain isolation between transistors and to provide for normal transistor action.
2.
θ

is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

NOTE:
3. On small-geometry, high-frequency transistors, it is very good practice never to take the Emitter Base Junction into reverse breakdown. To do
so may permanently degrade the h
FE
. Hence, the use of I
EBO
rather than V
(BR)EBO
. These devices are also susceptible to damage by
electrostatic discharge and transients in the circuits in which they are used. Moreover, CMOS handling procedures should be employed.
