In this paper we summarise the recent progress of novel HTS preselect bandpass filters for mobile communications applications. The filters with an 8-pole quasi-elliptic function response have been designed to cover a 15MHz sub-band which is centred at different frequencies within a receive band of 1710 to 1785MHz. The HTS filters have been fabricated using double sided YBa_2Cu_3O_7 thin films on MgO substrates with a size of 22.5x39mm. The filters have been tested in a vacuum cooler, showing excellent performance. The experimental results including power dependence, temperature dependence and non-linear characteristics are presented.
