Vanlong Technology Co., Ltd. (VTC) has introduced a new 480MHz series SAW Filters - SF480
used for satellite communications. These devices are housed in a rugged, hermetic, low

The SF480 series SAW Filters are ideal for DSB satellite receivers, which have
constant group delay characteristics, and improved ESD capability by integrated shunt
resistor. SF480 consists of 9 standard SAW Filters, with bandwidths ranging from 8.0MHz
to 23.5MHz, and very low insertion loss - 4.0dB to 4.5dB max at passbands. SF480 also consists of
2 types of double channels SAW Filter.
The Vanlong Technology group designs, manufactures and markets frequency control
products using the very latest techniques in both standard quartz crystal and surface acoustic
wave (SAW) based designs from DC to microwave frequencies. Products include quartz crystals
and crystal oscillators, SAW filters and SAW resonators, as well as ceramic products, which
used in telecommunication and data communication applications.
