Description

Cj < 1.0 pF max. @ 50 mW

The MA46600 series of microwave tuning varactors is

afamily of abrupt junction gallium arsenide devices

featuring Q factors in excess of 8000. This series is

specifically designed for broadband high Q tuning per-

formance (up to 8000 at -4 volts and 50 MHz) from L

through Ka band. Characteristics such as high reliabil-

ity, low leakage and close capacitance tracking be-

tween 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 packages 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 varactors

and are utilized in high frequency applications where

Q is premium.

Typical Performance Curves

Notes:

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

balanced with shielded test holders connected in place but open cir-

cuited.

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

tuning diode in a case style 30 with a CT14 between .36 and .44 pF and

a Q at -4 volts and 50 MHz ≥7500. The capacitance values and capaci-

tance ratios are for case style 30. Other case styles or chips will have

slightly different values.

3. All junctions are abrupt i.e., y = 0.50 ± .03.

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.

5. Case parasitics (Cp and Ls) are given for most case styles.
