Amplitude Balance: 0.75 dB max. VSWR (In/Out): 1.3:1 max. CW Input: 1 W max. Weight, nominal: 0.006 oz (170 mg) Operating Temp.: -- 55° to +85°C Typical QHZ-2A-60 Performance NOTES: 1. Tolerance on 3 place decimals ±.010(.25) except as noted. 2. Dimensions in inches over mm. General Notes: 1. The QHZ-2A series of CaseFree 3 dB Quadrature Hybrids has been designed for size and process compatibility with MMIC and similar devices. This series has narrow band applications and a profile height of less than 0.130" allowing mounting with similar miniature components within a low profile hermetic housing. 2. High performance remains uncompromised by the units’ miniature characteristics and very low weight. Additional models are being designed and will be available as catalog standard units. 3. All units can be supplied screened for compliance with specifications you designate for aerospace applications requiring the highest available reliability. 22Apr97 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
