description
The LTC6602 is a dual channel, matched, programmable bandpass or lowpass filter and differential driver. Together with its phase matching and dynamic range, it is well suited for filtering in RFID systems. With 2° phase matching accuracy between channels, the LTC6602 can be used in applications that require highly matched filters, such as transceiver I and Q channels. Thanks to gain programmability and fully differential inputs and outputs, implementations in most systems are simplified.
Both channels of the LTC6602 include a programmable low pass and high pass filter. If band-pass is required, set the low-pass filter to the high-frequency cutoff frequency. If low pass is required, the high pass filter can be bypassed. The filter cutoff frequency can be set with a single resistor to ensure an accuracy of 3%. Alternatively, an external clock can be used to control the filter cutoff frequency.
The LTC6602 operates from a single 2.7V to 3.6V supply and features a low power shutdown mode.

We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for dry type transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.
