Surface Mount Thin-Film Filters50Ω

DC to 40 GHz

The Big Deal

• Low passband insertion loss
• High rejection• Good power handling• Temperature stability -55°C to 125°C• High repeatability• RoHS complaint• Small size

Product Overview

Mini-Circuits’ Surface Mount Thin-Film filters offer low insertion loss and high rejection realized via Thin-Film on
Alumina substrate, using a sputtering process that can guarantee a enhanced Q and repeatable performance.
Low pass, high pass and bandpass surface mount thin-film designs can be realized with this technology. Usingthin-film manufacturing, we can guarantee repeatability on large batches of filters. Thin-film filters are small in sizewith high-quality, precise machining for applications where size is critical.

Key FeaturesFeature

Advantages

Low insertion loss

High Q material and sputtering process results in lower insertion loss, better SNR is obtained.

Fast roll-off (steeper skirts)

High selectivity results in better adjacent channel rejection and dynamic range

Wider stopband

Wide spur-free stopband results in better adjacent channel rejection and dynamic range

Temperature stabilityVery minimal change in electrical performance across temperature makes these filters suitable fora wide range of operating conditions.

Small Size

Various design techniques are employed to realize small size.

Bandpass Filter

1) Customer PCB’s ground pattern length (dimension A) can be similar to filter length.
2) Customer PCB’s ground pattern width (dimension B) can be similar filter width.
3) Dimensions C and D on Filter RF I/O detail and Customer PCB pattern can be closely match.
The dimensions of C and D on the Customer PCB pattern can be slightly larger to account forcomponent alignment tolerance (ground metal can be pulled back from RF I/O trace).
4) Recommend to use Solder mask at Customer PCB at outer area of filter pattern/ footprint
without any clearance.
5) Recommended to use Solder mask at I/O of Customer PCB with 5mil clearance from filter I/Oedge (dimension E).

Comments on component handling and solder attach
1) Avoid using soldering iron directly to the ceramic filter. This would lead to development of crack in thecomponent due to thermal shock.
2) Vacuum pick-up tool or plastic tweezers are recommended for handling the components. Extra careshould be taken not to scratch the filter or metal area.
3) Use 2-3 mil thickness stencil plate and screen print the solder. Refer below picture for recommended
stencil pattern to get the best solder attachment.

Solder location after screen print

4) Plugged ground vias in the PWB will improve attachment consistency.
5) Recommended to have a similar or closer test board material and thickness (refer Mini-Circuits
evaluation board for details) to minimize the CTE over the temperature range.
