HMC774 v00.1109 GaAs MMIC FundAMentAl MIxer, 7 - 43 GHz Features Passive: No DC Bias required High input iP3: +22 dBm High LO/rF isolation: 35 dB Wide iF Bandwidth: DC - 10 GHz Upconversion & Downconversion Applications Die size: 1.36 x 0.96 x 0.1 mm typical Applications The HmC774 is ideal for: • Point-to-Point radios 3 mixers - DOUBLe-BALANCeD - CHiP • Point-to-multi-Point radios & VsAT • Test equipment & sensors • military end-Use Functional diagram General description The HmC774 is a general purpose double balanced mixer chip that can be used as an upconverter or downconverter between 7 and 43 GHz. This mixer requires no external components or matching circuitry. The HmC774 provides excellent LO to rF and LO to iF isolation due to optimized balun structures. The mixer operates with LO drive levels of +13 dBm. The HmC774 wideband mixer exhibits consistent conversion gain and compression across its bandwidth. The HmC774 is also available in smT format as the HmC774LC3B. electrical Specifications, tA = +25° C, IF = 0.5 GHz, lO = +13 dBm* Parameter Frequency range, rF & LO Frequency range, iF Conversion Loss LO to rF isolation LO to iF isolation rF to iF isolation iP3 (input) iP2 (input) 1 dB Gain Compression (input) 20 7 min.

For applications not requiring operation to DC, this port should be DC blocked externally using a series capacitor whose value has been chosen to pass the necessary iF frequency range. For operation to DC, this pin must not source or sink more than 2 mA of current or part non-function and possible part failure will result.

One way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then attached to the ground plane (Figure 2). microstrip substrates should be brought as close to the die as possible in order to minimize ribbon bond length. Typical die-to-substrate spacing is 0.076mm (3 mils). Gold ribbon of 0.075 mm (3 mil) width and minimal length
