Description and Applications

The MA46450, MA46 47 0 and MA 46 41 0 series of tun-

ing varactors are hyperabrupt junction Gallium Ar-

senide diodes featuring constant gamma 1.0 (MA46450

series),1.25 (MA46470 series) or 1.5 (MA46410 se-

ries). These diodes offer high Q (up to 4000) permit-

ting excellent tuning 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 tolerances available.

Capacitance m atchin g at o ne or more bias volta ges is

also available. All diode types are available ina wide

selection of ceramic packages and in chip form.

The constant gamm a value of 1.0, 1. 25 or 1.5 avai lable

with these diodes enables the circuit designer to pro-

duce significant improvements in circuit performance.

Constant gamma tuning varactors permit more linear

VCO frequency tuning than do conventional hy-

perabrupt tuning varactors.These varactors are particu-

larly 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 (Cp and Ls) 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

available upon request. By adding the suffix A to the part number, a

tolerance 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 (VB) is measured at 10 microamps.

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