Two adjustable antenna varactor diodes from Renesas can be used for One Seg broadcasting 1

Renesas Technology Corp. recently announced the launch of two adjustable antenna varactor diodes (varicapdiodes) for portable and mobile terminals with digital terrestrial broadcasting capabilities: the RKV653KP has the industry's smallest size of 0.6mm x 0.3mm, while the RKV653KL comes in an extended package form.diodes

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 to handle digital terrestrial broadcasting frequencies for portable and mobile terminals (One Seg broadcasting), thereby promoting the integration of antennas with mobile phones with One Seg broadcasting capabilities. diodesThe RKV653KP and RKV653KL developed by Renesas Technology can meet the strict specification requirements for embedded varactor diodes to change the antenna resonance frequency. 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) and digital multimedia broadcasting (DMB). The characteristics of the two devices are as follows.diodes

(1) The industry's smallest size (RKV653KP)

The size of RKV653KP is 0.6mm × 0.3mm × 0.3mm (typical value), which is the smallest adjustable antenna varactor diode in the industry. This helps to easily integrate the antenna into the interior of mobile phones.diodes
