Description and Applications

The MA4P7441F-1091T is a surface mountable PIN

diode in a Non-Magnetic ( patent pending ) Metal

Electrode Leadless Faced (MELF) package. The

device incorporates M/A-COM’s proven HIPAX

technology to produce a low inductance ceramic

package with no ribbons or whisker wires. The

package utilizes M/A-COM’s new non- magnetic

plating process to provide an extremely low

permeability, hermetically sealed package.

Incorporated in the package is a passivated PIN

diode that is full face bonded on both the cathode

and anode of the chip to maximize surface area for

lower electrical and thermal resistance. The

MA4P7441F-1091T has been comprehensively

characterized both electrically and mechanically to

ensure repeatable and predictable performance.

This MA4P7441F-1091T Non-Magnetic device is

similar in electrical performance to the

MA4P4001F-1091T Magnetic part number.

The diodes are well suited for use in low loss, low

distortion, and high power switching circuits

applicable for high magnetic field environments from

HF through UHF frequencies. The lower thermal

resistance of this device provides excellent higher

average performance at RF power incident levels up

to 200 watts CW. This device is designed to meet

the most rigorous electrical and mechanical

requirements of MRI testing environments.

These SMQ PIN diodes are designed for high

volume tape and reel assembly. The rectangular

package design provides for highly efficient

automatic pick and place assembly techniques. The

parallel flat surfaces are suitable for key jaw or

vacuum pickup techniques. All solder able surfaces

are tin plated and compatible with reflow and vapor

phase soldering methods.
