In response to the demand for portable terminals, Renesas adjustable antenna varactor diodes have emerged 2

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.

(2) High capacitance variation ratio under low voltage conditions (RKV653KP and RKV653KL)

These new products can achieve the industry's highest capacitance change ratio of 2.7 (C1/C3 case) under low voltage conditions of approximately 3V,diode  which helps to achieve the wideband capability required for low voltage operation and adjustable antennas.

(3) Environmentally friendly lead-free and halogen-free specifications (RKV653KP)

RKV653KP adopts a lower electrode structure with electrodes located on the lower side of the package. The lower electrode pins are gold-plated, and the packaging body is made of halogen-free resin, diode effectively reducing the adverse effects on the environment at various stages of production and processing.

RKV653KL is also a lead-free product. Renesas will use halogen-free resin encapsulation in this product.

Other product details

RKV653KP and RKV653KL can achieve a high capacitance change ratio of 2.7 (in the case of C1/C3) under low voltage conditions of approximately 3V. This is achieved by optimizing the PN junction formation process conditions and epitaxial layers. diode In addition, the indicative variation of capacitance standard deviation for individual product characteristics has been limited to within ± 5% of the standard specification, which will help improve the receiving efficiency of the antenna.
