Description and Applications

The MA4P7418-10720T is a surface mount PIN

diode in a Metal Electrode Leadless Faced

(MELF) package. The device incorporates

M/A-COM Technology Solutions time proven

HIPAX technology to produce a low inductance

ceramic package with no ribbons or whisker

wires. Incorporated in the package is a fully pas-

sivated PIN diode chip that is full face bonded on

both the cathode and anode to maximize the sur-

face contact area for low electrical and thermal

resistance. The MA4P7418-10720T has been

comprehensively characterized both electrically

and mechanically to ensure repeatable and

predictable performance. The diode is well suited

for use in low loss, low distortion, high power

switching circuits. The low thermal resistance of

this device provides excellent high 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.

SMQ MELF PIN diodes are designed for high

volume tape and reel assembly. The rectangular

package design provides a highly efficient means for

automatic pick and place assembly techniques. The

parallel flat surfaces are suitable for key jaw or

vacuum pickup techniques. All solderable surfaces

are tin plated and compatible with reflow and vapor

phase soldering methods.
