A portable battery booster for providing a compact, light, and energy efficient battery to jump start a vehicle. The portable battery booster generally includes a housing, a battery means adapted to be received by the housing, a pair of cable means, each of the cable means having a proximal end and a distal end, the proximal end electrically connected to the battery means and the distal end detachably connected to a discharged battery of the vehicle. The battery is generally comprised of one or more batteries having the type of primary lithium-metal, rechargeable lithium-ion, and/or lithium-polymer and more specifically preferably comprised of lithium iron phosphate for fast charging, small size, and high performance. The battery may also be connected to one or more supercapacitors, an internal CPU, DC/DC converter, etc. to increase performance. The cable means includes jaws that detachably connect to the housing in a flush and sleek manner.

A low pass filter comprises a first series of transmission line elements connected between an input and an output; and a second series of shunt elements connected from the transmission line elements to a ground of the filter. At least one of the shunt elements has a distributed portion and a lumped portion. The distributed portion may comprise a tube mounted tangentially on a printed circuit board. The lumped portion may comprises a coil with a first lead connected to the first series of transmission line elements, and a second lead extending into the tube. A tuning element is moveably disposed in the tube. The tuning element may have an opening for receiving the second lead of the coil. The low pass filter may be used in a diplexer with one or more high pass filters. The diplexer may include power transmission apparatus.
