Back to top MODEL # DESCRIPTION APPLICATION PDI-1626 Channel Deletion Filters The PDI-1626 is a highly stable filter that will remove all signal information in any 6 MHz passband from 54 to 860 MHz with minimal effect on the adjacent channels. These filters are an 8 cavity design and are used primarily to delete an unwanted television channel on a cable system at a multiple dwelling unit or a node so a substitute channel or data may be inserted. The filters will pass 60/90 VAC at 14 amps as an extra cost option and are available in a 19” rack, wall mount, outdoor pedestal or strand mount housing with an optional built-in reinsertion point. Other customized versions are available on special order. PDI-1626HP PDI-1626LP Brick Wall Filters The PDI-1626HP and PDI-1626LP are sharp cutoff high and low pass filters used primarily for reinserting blocks of new programming in various portions of the CATV spectrum. They can also be used to split a CATV cable feed to interface with a fiber optics system. Cut off frequencies are customer specified. These filters are temperature and low frequency vibration stable. The units use “F” type connectors and are rack mounted utilizing 3-1/2” front panels. PDI-623 Bandpass Filters These single channel and multi channel bandpass filters are enclosed in our standard, rugged, weatherproof case for use at the tap in single channel applications. The model PDI-623 may also be utilized to improve overall system performance when interconnected with your headend processing equipment. PDI-EV619LP PDI-EVR-619LP Lowpass Filters The PDI-EV619LP & EVR619LP are lowpass filters that will pass all frequencies from DC to a prescribed frequency. They exhibit approximately 1dB of insertion loss for the desired frequencies with the exception of 3dB at the upper passband edge. They can be custom built to pass frequencies to 860MHz. The filters come with "F" fittings and are available for 19" rack or wall mounting. PDI-5411 Trunk Filter The PDI-5411 is a power passing, temperature stable filter designed for trunk or distribution cable applications. It is extremely valuable for blocking sub channel noise from motels and apartment complexes feeding back on a return path. All filter configurations, single channel notch, low pass, high pass, tier or bandpass are available. PDI-604 Single Channel Level Adjuster The PDI-604 is a filter designed to allow adjusting the level of single channel without effecting the adjacent channels. This device is a very cost effective and simple method adjusting levels that cause interference or overloads. It is ideal for antenna interference, private cable, and residential use. PDI-FV623 PDI-FVR-623 Noise Filter For Fiber Optic Systems The PDI-FV623 Wide Bandpass Filter allows signals between two customer specified 3 dB points (knees) to be passed.  Anything outside this bandwidth is rejected. PDI-EV643 PDI-EVR643 Pilot Carrier Trap The Pilot Carrier Trap suppresses pilot carriers used in AML transmissions.  The small size and temperature stability make it suitable to be installed in the AML receiver.  It is used to remove pilot carriers in CATV applications. PDI-FVX619 Split Band Filter For Fiber Optic Networks The PDI-FVX619 is a selective diplex filter wich provides customer specified 1 dB points that cross over so the passband is removed from the filter knee ensuring low group delay.   The passband has less than 1 dB ripple to 750 MHz. PDI-605CEQL PDI-605CEQV Cable Equalizer or Simulator The PDI-605CEQL and PDI-605CEQV are inline equalizing devices that either compensate or simulate specific lengths of cable. They are designed to the highest frequency (pivot point) of any system, up to 1 GHz. PDI-DFN619 High Performance Diplex Filter Network The PDI-DFN619 high performance filters are used to seperate or combine sub-VHF and VHF frequencies.  Designed for headend applications to launch and/or combine upstream and downstream signals. PDI-619-TF Tier Filter PDI's model PDI-619-TF multi channel filters are designed with unique hybrid circuitry developed to achieve the tightest adherance to specifications in the industry.  Filters are available in any configuration required. PDI-DPFO Outdoor Diplex Filter Network The PDI-DPFO is a band-splitter in an outdoor housing. It separates a desired spectrum into a low band and high band or conversely combines these bands into a common output. These filters are used to insert or remove sub-band signals from distribution systems. They help to control the flow, level and direction of television and data in the distribution system. The filters are contained in a sealed housing, heavily tin plated to prevent rust with a grounding boss for safety. PDI-EVBE1G Bandwidth Expander The PDI-EVBE1G is deployed in situations when a channel elimination filter network or any filter network needs to extend it’s bandwidth to 1 GHz. This is necessary because many channel elimination filters in use have limited bandwidths of 400, 450, or 550 MHz. Typical operation of the device allows for total compatibility of the EVBE1G unit with all brands of channel elimination filters. In certain situations there could exist custom tuning requirements. PDI-PBPO PDI-EVPBP Power Bypass 14 Amp The PDI-EVPBP and PDI-PBPO are bypass power devices that route power around passive devices that cannot be power operated. The PBPO is a strand mount outdoor device. This unit is capable of handling 14 amps 60/90 VAC/VDC. The RF pass band is 5 MHz to 1 GHz. The EVPBP is a rack mounted indoor device that routes power around passive devices tha cannot be power operated. PDI-HPF Reverse Filters 5-40 MHz The PDI-HPF is a high-pass filter that suppresses all spurious sub low noise from entering the return path of a CATV system by blocking 5 - 40MHz and passing 54MHz through 1GHz. Other window versions are available on special order. PDI-EV623 PDI-EVR623 General Bandpass Filters The PDI-EV623 & PDI-EVR623 are very stable bandpass filters with good selectivity used to eliminate adjacent channel or off air interference in CATV or similar headends. They cover the frequency spectrum from 5 to 860 MHz. They offer excellent operating characteristics such as high return loss, low insertion loss and high undesirable signal rejection. They are available for either wall or rack mounting.
