Microstrip Transmission Lines

ATP offers three different types of 50 Ohm transmission lines: single line, single line with two rows of tuning pads, and single line with four rows of tuning pads. ATP Transmission Lines have a fixed width and adjustable lengths, no mask purchase required. Lines are continuous and can therefore be diced to any size. In-stock lengths are in 0.010" (0.254mm) increments, up to 0.500" (12.70mm).

Note: By design, these parts may occasionally have burrs/tails since ATP is dicing through Au. There is no pull back in these designs.

ATP will guarantee to MIL-STD-883, Method 2011.10, Test Condition D, using a 1mil wire, on ATP standard products.

Material: Asfired Alumina 99.6% (polished Alumina available upon request)

Metallization front and back sides:

TiW = 300–800Å (0.03µm–0.08µm)

Au = 120µ" (3 microns) minimum

Delivery: Ships in 24–48 hours (in-stock lengths only) for Asfired Alumina. Polished Alumina will be special order.
