(DRIVERLESS)
Miniature Broadband SP2T Switch with Integrated Driver

F9120
(With INTEGRATED Driver)

MODELS 9120-500 AND 9220-500
These switches provide high-performance characteristics over a multi-octave frequency range. Model 9120-500 covers the frequency range of 1 to 18 GHz; Model 9220-500 covers the frequency range of 0.2 to 4 GHz. Both models use an integrated circuit assembly of a series-shunt configuration of PIN diodes mounted in a microstrip transmission line as shown below.

Port Control
By applying positive current to a bias terminal, the associated port is OFF since the corresponding shunt diodes are biased to a low resistance and the series diode to a high resistance. With negative current at the bias terminal, the converse conditions are established and the port is ON. Since bias terminals are individually available for both ports, the user has the option of any combination of ports ON or OFF.


MODELS 9120T-500, 9120W-500 AND 9220T-500
These switches are non-reflective versions of the switches described to the left. They are constructed in the configuration shown below.

Series 91T, 92T and 91W schematic diagram

Series 91T, 92T and 91W schematic diagram
 

When positive current is applied, the port is OFF since the associated series diodes are back-biased to a high resistance. At the same time, the corresponding shunt diode is biased to a low resistance, and the impedance at the port is then effectively that of the 50 ohm resistor in series with the shunt diode. When applying negative current, the converse conditions are established and the port is ON.

Note that when all output ports are OFF, a high VSWR will be present at the common port.

MODEL 9120AH-500
This switch has the same circuit topology as the 9120-500 except it is equipped with high-speed diodes to achieve rise and fall times of 10 nsec.

MODEL 9120AHT-500
This switch is similar to the 9120AH-500 except it includes a terminating network as shown below.

SERIES F91/F92
The Series F91/F92 units are the same as the Series 91/92 units except they are equipped with integrated drivers that are powered by +5 and -12 to -15V supplies. The proper currents required to switch the ports ON or OFF are provided by the drivers, which are controlled by external control signals. Standard units are wired so that a port is ON with the application of a logic "0" control signal.

SERIES G91 and G92

    • Frequency range (Series G91): 1 to 18 GHz
    • Frequency range (Series G92): 0.2 to 4 GHz
    • Reflective and non-reflective models
    • Low VSWR and Insertion loss
    • Up to 60 dB isolation
    • Positive DC supplies only
    • Miniature size, light weight



Series G91 and G92 Miniature Broadband SP2T switch Model G9120

SERIES G91 and G92
Operating from +5 and +15V power supplies only, the G-series switches provide high performance characteristics at relatively high speeds over multi-octave frequency ranges. The series includes low Insertion loss and high isolation models in both reflective and non-reflective configurations. Series G91 units cover the frequency range of 1 to 18 GHz; Series G92 units cover the frequency range of 0.2 to 4 GHz. The design is based on an integrated circuit assembly of PIN diodes mounted in a microstrip transmission line as shown below. The currents required to switch the ports ON or OFF are provided by the integrated driver, which is controlled by external TTL logic signals.
