30SPA0557

      30SPA0557 is a 27.0-32.0 GHz GaAs MMIC power amplifier.Here you can get some information about its features.It has five features as follows.The first one is that it is  a ka-band 2W power amplifier.The second one is that it has 21.0dB small signal gain.The third one is that it has +33.0 dBm saturated output power.The fourth is that it has 100% On-wafer RF, DC and output power testing.The fifth one is that it has 100% visual inspection to MIL-STD-883 Method 2010.

      Then we give you the general situation about 27.0-32.0 GHz GaAs MMIC power amplifier. This MMIC uses Mimix
Broadband's 0.15 m GaAs PHEMT device model technology, and is based upon electron beam lithography
to ensure high repeatability and uniformity. The chip has surface passivation to protect and provide a rugged part with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach
process. This device is widely used in  Millimeter-wave Point-to-Point Radio, LMDS, SATCOM and VSAT.

      Then we have to understand the absolute maximum ratings and characteristics of 30SPA0557 if you want to purchase the product.The supply voltage (V_d) is +6.5VDC.The supply current (I_d1,2,3) is 165,415 and 790 mA respectively.  
The gate bias voltage (V_g) is +0.3 VDC.The input power (Pin) is TBD.The storage temperature (T_stg) is from -65 to +165 .
      The following is the electrical characteristics of 30SPA0557(ambient temperature T = 25 ).There are ten electrical characteristics as follows.The first one is about the frequency range.The minimum is 27.0GHz and the maximum is 32.0GHz. The second one is the input return loss which is 10.0dB.The third one is the output return loss which is 10.0dB.The fouth one is the small signal gain which is 21.0dB. The fifth one is the gain flatness which is +/-1.0dB.The sixth one is the reverse isolation which is 50.0dB.The seventh one is the saturated output power which is +33.0dBm.The eighth one is drain bias voltage.The typical is +5.0VDC and the maximum is +6.0VDC.The ninth one is gate bias voltage. The minimum is -1.0VDC,the typical is-0.7VDC and the maximum is +0.0VDC.The tenth one is about the supply current.On the condition that V_d=5.0V and V_g=-0.7V typical,the typical of supply current (I_d1) is 125mA and the maximum is 150mA;the typical of supply current (I_d2) is 315mA and the maximum is 375mA;the typical of supply current (I_d3) is 600mA and the maximum is 720mA.
