TUNABLE FILTERS

Eiwave designed and developed tunable filters in HF ,UHF,VHF upto L band . low power (varactor based )  and high power(pin diode based)  are available in various miniature packages .we have developed filters with through hole and SMD packages  .High degree of flexibility in design makes filters adjustable of various filter bands. Eiwave is looking forward for further smaller packages with better performance. detailed description of available filter variants are given below…

PICO FILTER'S

The PiCo filters are designed for low power applications   .the ultra miniature size of the filter makes it unique  with  this specifications. It comes with an overall dimension of 20*20*5.5( all dimensions are in mm). Module is designed with surface mount package with metallic shield. Filters are available over the frequency range of 30MHz-1000MHz .

 

VOLTAGE TUNABLE FILTER'S

Voltage tunable filter is available from 200MHz to 1000MHz. Filter is tunable with dc voltage changing from 4V to 20V. filter comes with a through hole package with an over all dimension of 25*30*11 (mm).detailed information in given below

 

MICRO FILTER'S

The low power tunable filter (30MHz to 1000MHz) is a miniature tunable Band-pass filter using varactor diodes to reduce size and power consumption.digitally tunable filters are available with different bandwidth depending on requirement. The device overall size fitting in (12.7×25.4×38.1) all dimensions are in mm)) .

 

ULTRA HIGH REJECTION FILTER'S

5 pole Tunable filters are designed with ultra high rejection. Five poles filter structure ensures sharp cut off for the filter. The filter requires a s single 5V supply .The digital interface format is SPI serial ,all control logic are 3.3V logic only. The miniature filter comes with surface mount package with overall size fitting in (42x47x8(mm)).

 

MINIFILTER

The tunable filter (1.5MHz to 400MHz) is a miniature tunable Band-pass filter with high performance . tunability is achieved through PIN diodes to deliver high dynamic range . with over all size fitting  in 60*25*14.78(all dimensions are in mm).the filter module comes with through hole package, all interfaces and pin out configurations are given below.

 

MINI TUNABLE FILTER BANK

The tunable filter (1.5MHz to 30MHz) is a miniature tunable Band-pass filter with high performance . tunability is achieved through PIN diodes to deliver high dynamic range . with over all size fitting  in 80*65*14.78(all dimensions are in mm).the filter module comes with through hole package, all interfaces and pin out configurations are given below.

 

MINI SMD FILTERS

The Tunable filter (30MHz to 520MHz) is a miniature tunable Band-pass filter with high performance . tunability is achieved through PIN diodes to deliver high dynamic range . with over all size fitting  in 61×44.5×9.8(all dimensions are in mm). It has the flexibility to select between serial and parallel tuning control.
