Renesas launches adjustable antenna varactor diode for digital terrestrial broadcasting 1

Renesas recently announced the launch of two adjustable antenna varactor diodes (varicap diodes) for portable and mobile terminals with digital terrestrial broadcasting capabilities. The RKV653KP is claimed to have the industry's smallest size of 0.6 × 0.3mm, while the RKV653KL comes in an extended package form. The sample supply started from Japan on August 3, 2006.

Adjustable antenna is an antenna that can change its resonant frequency to effectively receive various frequency bands. This will help to utilize small packages and adjustable antennas for portable and mobile terminals (One Seg broadcasting, a terrestrial digital broadcasting standard used in Japan for portable and mobile terminals). diodes The 6MHz frequency band is divided into 13 bands, and it uses the middle band. This service began in April 2006. ）The digital terrestrial broadcasting frequency promotes the integration of antennas with mobile phones with One Seg broadcasting capabilities. The RKV653KP and RKV653KL developed by Renesas Technology can meet the strict specification requirements for embedded varactor diodes to change the antenna resonance frequency. diodes These two products can be used for One Seg broadcasting and other digital broadcasting services, such as adjustable antennas for digital video broadcasting handheld devices (DVB-H * 3) and digital multimedia broadcasting (DMB * 4).
