Passive intermodulation free multilayer thermal blanket
First Claim
1. Passive intermodulation free thermal blanket apparatus comprising:
- a reflector stack comprising multiple polyimide layers having metallized film on one side thereof;
a binding layer that secures the reflector stack together; and
outer cover layers that wrap around the binding layer and reflector stack to cover an outer surface of the thermal blanket and form a hem on an inner surface of the thermal blanket.

Abstract
Thermal apparatus that reduces passive intermodulation products generated on a satellite or other spaceborne vehicle. Exemplary passive intermodulation free thermal blankets comprise a reflector stack including multiple polyimide layers with metallized film on one side thereof, a binding layer that secures the reflector stack together, and an outer cover layer that wraps around the binding layer and reflector stack to cover an outer surface of the thermal blanket and form a hem on an inner surface of the thermal blanket. Multiple small thermal blankets or patches may be bound together using grounding inserts and polyimide tape to form a quilt-like assembly. The quilt-like assembly is enclosed by an outer cover layer that wraps around the multiple patches to cover one surface thereof and form a hem on an opposite surface thereof.
