HMC451LP3/HMC451LC3/HMC441LC3B_2nd harmonic level

Question

Dear team, 
 
 We are reviewing the devices for the test and measurement application. 
 Coule we know the 2nd harmonic level about the following devices? 
 1. HMC451LP3 
 2. HMC451LC3 
 3. HMC441LC3B 
 
 We are looking forward to your advice. 
 Thank you 
 Regards, 
 Josh

Unfortunately, all I can find is IP2 data at a relatively low level (0 dBm and +5 dBm per output tone). However with this data you can estimate what the second and third harmonic distortion would be at the levels you are interested. Here are the equations

Equation 
 Comments

OIP3(dBm)=Po(dBm)-(IMD3(dBc)/2) 
 imd2 should be a negative number

OIP2(dBm)=Po(dBm)-IMD2(dBc) 
 imd3 should be a negative number

HD2(dBc) = IMD2(dBc) - 6 dB 
 IMD2 should be a negative number

HD2(dBc) = Po(dBm) - OIP2(dBm) - 6dB 
 HD2 should be a negative number

HD3(dBc) = IMD3(dBc) - 9.54 dB 
 imd3 should be a negative number

HD3(dBc) = 2 x (Po(dBm) - OIP3(dBm) ) - 9.54 dB 
 HD3 should be a negative number

The three devices have the following OIP2 performance. 
 1. HMC441LC3B: 42.6 dBm (16 GHz, 5V/90mA Bias): HD2 Estimate at 19.5 dBm Po = -29.1 dBc 
 2. HMC451LP3: 37 dBm (14 GHz, 5V/120mA Bias): HD2 Estimate at 20 dBm Po = -23 dBc 
 HMC451LP3: 37 dBm (16 GHz, 5V/120mA Bias); HD2 Estimate at 20 dBm Po = -23 dBc 
 
 3. HMC342LC4: 25.4 dBm (14 GHz, 3V/43mA Bias): HD2 Estimate at 7 dBm Po = -24.4 dBc 
 HMC342LC4: 28.4 dBm (16 GHz, 3V/43mA Bias) HD2 Estimate at 7 dBm Pout = -27.4 dBc)
