HXI’s HAFM Series of active multipliers is available in models ranging from 30
to 100 GHz. A wide variety of multiplication factors from X2 up to X6 provide
the customer with design flexibility for many applications. Basic multiplier
circuits can be cascaded to achieve higher order multiplication factors.
Active multipliers are often used in LO chains in radars and communication
systems, allowing the use of low phase noise frequency sources at lower
frequencies. Multipliers also find use in frequency extenders for test equipment.

HXI’s HLNA Series of Low Noise Amplifiers covers the frequency ranges from 20 to 100+ GHz. A wide variety of gain and bandwidth combinations are available to provide the designer with a solution for most applications. Custom designs are available and in many cases NRE is not required. MMIC technology is employed for high reliability and repeatability.

Renaissance offers a Ku-band Surface Mount Isolator that has similar electrical performance as the drop-ins but with the advantage of being pick and place compatible processed and therefore ideal for high volume production designs. With insertion loss of 0.5 dB and 20 dB return loss, it is well suited to reduce VSWR ripples due to RF components that have high VSWR.
HXI’s HDA040-069 Digital Attenuator covers the range from DC to 40 GHz in 6-bit operation. Attenuation bit values are 0.5 dB (LSB), 1, 2, 4, 8 and 16 dB for total attenuation of 31.5 dB above the attenuator insertion loss. Low bit errors and
RMS phase errors are characteristics of this attenuator. The attenuator is useful for
communication systems, radars and in test equipment.
HXI’s HMI AND HMC series broadband ferrite junction isolators and circulators are available from 18 – 120 GHz. They utilize a low loss H-plane structure in a modified Y-junction format to provide minimum loss with maximum isolation and bandwidth.
2 GHz bandwidths with 20 dB of isolation are standard. Wider bandwidth, high power handling and magnetic shielding are available in select units.
The isolators are commonly utilized to buffer mismatches and are often used on amplifier and oscillator outputs. Circulators are commonly employed as signal duplexers on transceivers having a single antenna. The in-line port orientation makes the mechanical interface more convenient than standard Y-junction types. Access pockets
on the top and bottom allow for blind flange mating.
