Ka-Band Mixer-Preamplifier
Spacek Labs Model P34-1 is a low-noise mixer-preamplifier that covers a 26 GHz bandwidth in Ka-band. The LO + RF bandwidths are 2 GHz wide in WR-28. The IF band is 10 – 500 MHz. LO power input is +10 dBm. RF to IF gain is 25 dB typical and the DSB noise figure is 2.5 dB typical and 3.0 dB maximum. Bias is 25 mA @ +15 volts.

Spacek Labs Model AW-8X is an 8X multiplier with an output covering all of W-band, Input frequency is 9.35 to 13.75 GHz @ +5 to +10 dBm. Output frequency is 75 to 110 GHz @ + 3 dBm typical, 0 dBm minimum. The assembly incorporates a Spacek Labs 57 GHz low pass filter after the X4 multiplier to reject any unwanted harmonics. Spurious signals are 20 dBc typical. The input bias requirement is 0.9 Amp @ +8 volts. |

COLFET Low-Noise Calibration Sources |
Spacek Labs Model CS-K Low-Noise COLFET Calibration Source offers a new way to calibrate K-Band radiometers. Instead of a liquid nitrogen-cooled load, a small waveguide-output source (K-connector optional) radiates 33 to 60 Kelvin's over 20-24 GHz when biased by +8 VDC, 100 mA max. The CS-K (Fig. 1) operates at room temperature so no cooling is required. Its integral voltage regulator ensures the constant noise-temperature output, and can also be TTL controlled. Also available are high-temperature output noise sources providing ~20 dB ENR when biased (+10 to +17 mA at >15 V DC typ). The high-ENR and COLFET noise sources are available for K-Band (20-24 GHz) water-vapor radiometers and for V-Band (Fig. 2) covering 50-60 GHz for oxygen-line radiometers. |
