Description

The MA46600 series of microwave tuning varactors is a

family of abrupt junction gallium arsenide devices featur-

ing Q factors in excess of 8000. This series is specifically

designed for broadband high Q tuning performance (up

to 8000 at -4 volts and 50 MHz) from L through Ka band.

Characteristics such as high reliability, low leakage and

close capacitance tracking between diodes are typical of

these devices. Standard capacitance matching is ± 10%,

but closer matching is available upon request. All diode

types are available in a wide selection of ceramic pack-

ages as well as in chip form.

Applications

The MA46600 series of tuning varactors can be used for

both broad and narrow band tuning through Ka-band.

Typical applications include solid state tuning of VCOs

using transistors or Gunns as well as voltage tunable

filters and amplifier circuits. The GaAs abrupt junction

tuning varactors offer the highest Q of any tuning varac-

tors and are utilized in high frequency applications where

Q is premium.

Notes:

1. Capacitance is measured at 1 MHz on a bridge which has been bal-

anced with shielded test holders connected in place but open circuited.

2. All GaAs tuning varactors are available in any case style shown in this

bulletin as well as in chip form. When ordering, specify the desired

case by adding the case designation as a suffix to the model number,

i.e., MA46601-30. For example, a MA46601-30 specifies a 30 volt tun-

4. Total capacitance ratios will vary with case choice due to differences in

case capacitance (Cp). Figure 1 shows the ratio for the 30 case style.
