The HAFM Series of active multipliers is available in models ranging from 18 to 140 GHz. A wide variety of multiplication factors from X2 up to X12 provide the customer with design flexibility for many applications. These multipliers 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 frequency sources at low frequencies. Multipliers also find use as frequency extenders for test equipment.
Standard units are available that can be driven with 10 mw or less. Outputs to 0.5 W are obtained with P-HEMT and abrupt varactors. Isis stacked varactors are used for higher drive levels from 500 mW to several watts. Power outputs of 2W @ 35 GHz, 300 mW @ 50 GHz, and 100 mW @ 94 GHz have been obtained.
The HMM Series Multipliers cover the range from 18 - 100 GHz. A wide variety of doubler and tripler designs provide the designer with a solution for many applications. Full waveguide band units are available through 100 GHz. These multipliers are used as frequency extenders in test equipment and as mixer LO's. Standard units are available to be driven with 10-40 mW and high power options are available for 100 mW drive. No DC bias is required.
The HMM Series Multipliers use a pair of GaAs beam lead diodes on a planar circuit mounted in a low loss waveguide structure. Their high bandwidths and small size make them an ideal choice in subsystems. The HFM family of varactor multipliers are used where higher power handling is required.
