	PCC - Crossguide Directional Couplers	PCC series crossguide directional couplers are offered for the frequency range of 18 to 110 GHz in seven waveguide bands. The standard coupling level is 20 dB with moderate operation bandwidth and directivity. The couplers are typically used for power sampling or frequency monitoring with minimum signal loss on the main transmitting path. The crossguide couplers perform similar system functions while delivering much shorter insertion length and lower insertion loss compared to their counterpart, multi-hole directional couplers. Because of its unique features, these directional couplers are ideal candidates for system integration.
	PCM - Multi-Hole Directional Couplers	PCM series multi-hole directional couplers are offered for the frequency range of 18 to 110 GHz in seven waveguide bands. The standard coupling levels are 3, 6, 10, 30 and 40 dB with full waveguide operational bandwidth. The high directivity is achieved via low VSWR built-in termination. The couplers are typically used for power sampling or frequency monitoring with minimum signal loss on the main transmitting path. The multi-hole couplers are especially used in the test setups where power reflection measurement is required.
	PDC - Waveguide Diplexer	PDC series waveguide diplexers are available in major communication frequency bands. Existing products offer narrow frequency band to cover common North American point-to-point digital radio frequency bands from 18 to 40 GHz. These diplexers consist of two E-plane bandpass filters (BPF) and a circulator. The critical element of E plane BPF is designed by using proprietary simulation tool and fabricated by conventional low cost printed circuit techniques. The diplexers require no tuning, which allows low cost, high volume production. Typical insertion loss is from 1.0 to 2.0 dB, depending on the channel bandwidth and isolation. The frequency stability is around -0.4 MHz/¦C with low cost aluminum housing. The existing product performance is illustrated as follows. Other frequency bands are available upon request.
	PTC - Waveguide to Coax Adapters	PTC series waveguide to coax adapters are available in 9 waveguide bands covering the frequency range of 8.2 to 70 GHz. The adapters covering 8.2 to 60 GHz frequency range are designed for full waveguide band operation, while V band one is for 50 to 70 GHz. These adapters are specially designed with exceptional high performance. SMA male or female connectors are standard coaxial line interfaces for WR-90, WR-75, WR-62 waveguide adapters. 2.92 mm (K) male or female connectors are for WR-42 and WR-28 waveguide adapters, while 2.4 mm male or female connectors are for WR-22 and V male or female connectors are for WR-19 and WR-15 waveguide adapters. The adapters are ideal choices where the waveguide to coaxial transitions are required.
	PWS - Waveguide Straight Sections	Waveguide straight sections (PWS) offer the inter-connections between the waveguide ports and are available in 1í¦ to 8í¦ standard length in 1í¦ incremental as well as customer-specified lengths.
	PWT - Twist Waveguides	Waveguide twists (PWT) allow changing the orientation of the waveguide port and are available with the twisting angle of 45° or 90°.
	PTW - Tapered Waveguide Transitions	PTW series rectangular waveguide taper transitions are offered to cover frequency range of 18 to 110 GHz. These transitions are manufactured with EDM technique to ensure high mechanical tolerance and ruggedness. Typical VSWR for these transitions is 1.05:1. The transitions are used for smooth transition between different waveguide size with minimum loss. The outline drawing for these transitions is WT-E-6.
	PWM - Waveguide Termination Loads	Waveguide termination loads (PWM) are useful when a matched port termination is required. The standard termination loads offer less than 1.10 VSWR and up to 10.0 watts power handling. Higher power handling versions are offered as custom-specified option.
	PCT - Matched Hybrid Tees (Magic Tees)	PCT series waveguide matched hybrid tees (Magic Tees) are available in microwave and millimeterwave frequency bands up to 110 GHz. These hybrid tees are matched power dividers or combiners for many system applications. These hybrid tees are four port couplers.
	PFB - Waveguide Bandpass Filters	PFB series waveguide bandpass filters (BPF)are available in millimeterwave frequency bands up to 110 GHz and major communication frequency bands. There are two types of configurations are employed in these bandpass filters.
	PFH - Waveguide Highpass Filter	PFH series waveguide highpass filters (PHF) are available in major communication frequency and Radar bands. The frequency coverage is up to 110 GHz in 8 waveguide bands. These filters are designed to offer sharp cut off and high attenuation in the stop band and low insertion loss in the pass band.
	PPD - Coax Power Dividers	PPD series coax standard power dividers are available in 2 way and 4 way power splitting configuration to cover the frequency range of 18 to 45 GHz frequency range. Unlike their resistive counterpart, these power dividers offer extremely low insertion loss and high port to port isolation while having moderate operating bandwidth. The power dividers are ideal choices where the precise power splitting is required. The power dividers can be used as power combiners.
	PFL - Waveguide Low Pass Filters	PFL series waveguide low pass filters (PFL) are available in millimeterwave bands to cover the frequency range up to 110 GHz. The high pass nature of waveguide dictates the low end cut off for standard model. Both low end and high end cut off frequencies can be specified as a custom order. In fact, the waveguide low pass filters are the bandpass filters with very broad pass band. They are ideally suited for broad band system applications, such as EW system, instrumentation and harmonic and spurious rejections, etc.
