Abstract
A tunable radio frequency (RF) resonator may include an RF cavity core defining an RF cavity. The RF cavity core may include a post positioned within the RF cavity. The tunable RF resonator may further include a flexible membrane covering the RF cavity. A gap may be defined between the flexible membrane and the post. An actuator may cause movement of the flexible membrane and vary the distance between the membrane and the post. The RF cavity core is may be injection molded plastic with a metalized electroplating.
Claims25
A tunable RF resonator, comprising:
- an RF cavity core defining an RF cavity, the RF cavity core further comprising a post positioned within the RF cavity,
- a flexible membrane covering the RF cavity, wherein a gap is defined between the flexible membrane and the post;
- and
- an actuator configured to cause movement of the flexible membrane and vary the distance between the membrane and the post,
- wherein the RF cavity core is an injection molded plastic with a metalized electroplating.
A tunable RF filter, comprising:
