A recently granted patent (Publication Number: US11882667B1) discloses a replacement lid assembly designed for an RF amplifier housing in a hybrid fiber-coaxial (HFC) network. The assembly includes a lid body portion with a first lid chamber for housing electronic components, a lid rim with a lid gasket channel, and an integrated power supply in a second lid chamber. Heat transfer fins are also present on the lid body portion to manage heat dissipation effectively. Additionally, the lid gasket is made of silicone and includes both conductive and non-conductive portions for optimal performance.

Moreover, the patent also covers a housing for an electronic device intended for outdoor use, featuring a base with a base chamber and a base gasket channel, along with a lid assembly with similar components as the replacement lid assembly. The lid assembly includes an integrated power supply and heat transfer fins for efficient heat management. The lid gasket, in this case, also includes conductive and non-conductive portions. Furthermore, the patent extends to an RF amplifier for HFC networks, where the lid assembly can be removed without disconnecting the amplifier circuitry, thanks to its design. The amplifier circuitry is capable of amplifying RF signals up to 1.8 GHz and includes connector ports for cable connections, along with a lid gasket with conductive and non-conductive portions for enhanced functionality.
