l- flatpack outline IQF-20L series i&q networks 3 to 6 ghz / low loss / excellent phase and amplitude balance / hi-rel hermetic package fo r f ur t he r infor ma tion con t ac t merr ima c / 41 fairfield pl., west caldwell, nj, 07006 / 973 -575-1300 / fax 973 -575-0531 general notes: 1. i & q networks are integrated devices that produce two quadrature-phased, equal amplitude signals when fed rf and lo signals. 2. comprised of standard components, these units are optimized for high accuracy at a specified lo frequency and maintain specified performance across a bandwidth of 10% of the lo frequency. 3. i & q networks can also be used in digital systems as a qpsk demodulator where it recovers two data channels from the incoming phase information. the qpsk input is applied to the rf port while the recovered carrier is applied to the lo port resulting in the two independent data outputs at the i and q data ports. 4. merrimac i & q networks comply with the relevant sections of mil-m-28837 and can be supplied screened for compliance with additional specifications for military and space applications requiring the highest reliability. principal specifications rf/lo ? i/q output model frequency bandwidth number f o , ghz mhz IQF-20L-****b 3 to 6 dc - 150 for complete model number replace **** with desired lo center frequency in mhz general specifications rf/lo input characteristics ? rf bandwidth: 10% of f o impedance: 50 w nom. vswr: 2.0:1 max. rf power level: 0 dbm max. lo power level @ f o : +10 dbm nom. i & q output characteristics output impedance: 50 w nom. conversion loss (rf to i or q): 8 db typ.,12 db max. if quadrature bal.,(i to q),@ 100 khz if phase (lo=f o ): 2nom., 3max. phase (lo=f o 5%): 2nom., 5max. ampl. lo=f o ): 0.3 db max. ampl.
