Description

The MA46450, MA46470 and MA46410 series of tuning

varactors are hyperabrupt junction Gallium Arsenide

diodes featuring constant gamma 1.0 (MA46450 series),

1.25 (MA46470 series) or 1.5 (MA46410 series). These

diodes offer high Q (up to 4000) permitting excellent tun-

ing performance from VHF through Ka band. Each part in

this series exhibits the large change in capacitance versus

bias voltage characteristic of hyperabrupt junctions. The

standard capacitance tolerance is ±10%, with tighter toler-

ances available. Capacitance matching at one or more bias

voltages is also available. All diode types are available in

a wide selection of ceramic packages and in chip form.

TYPICAL JUNCTION CAPACITANCE vs TUNING VOLTAGE

Applications

The constant gamma value of 1.0, 1.25 or 1.5 available

with these diodes enables the circuit designer to produce

significant improvements in circuit performance. Constant

gamma tuning varactors permit more linear VCO frequen-

cy tuning than do conventional hyperabrupt tuning varac-

tors. These varactors are particularly well suited for use in

voltage tuned filters, analog phase shifters, and modulator

circuits.

Notes:

1. All GaAs tuning varactors are available in chip form as well as the case

styles shown on the following page. When ordering, specify the desired

case by adding the case designation as a suffix to the type number.

2. Case parasitics (C and L ) are given for most case styles along with

case outlines in the appendix. The Cp values listed typically have toler-

ances of ±0.02 pF.

3. The nominal tolerance at -4 Volts is ± 10%. Closer tolerances are avail-

able upon request. By adding the suffix A to the part number, a toler-

ance of ± 5% at -4 Volts is guaranteed.

4. The values guaranteed for gamma are measured on unpackaged

chips. The total capacitance versus bias voltage curve will deviate

slightly from the chip capacitance versus bias voltage curve due to the

package parasitic capacitance (Cp).

5. Capacitance is measured at 1 MHz.

6. Reverse voltage (V ) is measured at 10 microamps.

7. The total capacitance and capacitance ratios shown are for diodes

housed in case style 30. Other case styles will result in different val-

ues.
