Abstract
A disk drive is disclosed comprising a disk, a head actuated over the disk, a preamp, and an interconnect for coupling the head to the preamp. The interconnect comprises a first transmission line stacked with a second transmission line, and a dielectric between the first transmission line and second transmission line. The transmission lines form an approximation of at least one inductor/capacitor ladder network and an approximation of at least one inductor/capacitor lattice network. The lattice network comprises a first leg and a second leg, and a cross-over hub for interconnecting the first leg and the second leg.

A disk drive comprising:
- a disk;
- a head actuated over the disk;
- a preamp;
- and
- an interconnect comprising a first transmission line stacked with a second transmission line, and a dielectric between the first transmission line and second transmission line, wherein the transmission lines form an approximation of at least one inductor/capacitor ladder network and an approximation of at least one inductor/capacitor lattice network, the inductor/capacitor lattice network comprising:
- a first leg comprising part of the first transmission line stacked with part of the second transmission line, wherein the transmission lines are shorted at a first end of the first leg and open at a second end of the first leg;
- a second leg comprising part of the first transmission line stacked with part of the second transmission line, wherein the transmission lines are shorted at a first end of the second leg and open at a second end of the second leg;
- and
- a cross-over hub for interconnecting the first leg and the second leg.
A suspension for use in a disk drive, the suspension comprising an interconnect comprising a first transmission line stacked with a second transmission line, and a dielectric between the first transmission line and second transmission line, wherein the transmission lines form an approximation of at least one inductor/capacitor ladder network and an approximation of at least one inductor/capacitor lattice network, the inductor/capacitor lattice network comprising:
- a first leg comprising part of the first transmission line stacked with part of the second transmission line, wherein the transmission lines are shorted at a first end of the first leg and open at a second end of the first leg;
- a second leg comprising part of the first transmission line stacked with part of the second transmission line, wherein the transmission lines are shorted at a first end of the second leg and open at a second end of the second leg;
- and
- a cross-over hub for interconnecting the first leg and the second leg.
