Ultra-low noise, ultra-high PSRR low dropout (LDO) linear regulators are key to power precision sensors, high speed data converters, frequency synthesizers and other noise-sensitive RF and microwave devices. Power by linear offers an outstanding family of robust positive and negative LDOs that produce ultra-low output noise and ultra-high power supply ripple rejection that cover a wide input voltage range, from 1.8 to 20 V, –20 to – 1.8 V and a wide output current range, from 200 to 500 mA.
Integrated Receiver Module
SSR-3331834012-28-S1 is an integrated receiver module. The receiver has a typical conversion gain of 12 dB with a typical noise figure of 4 dB in the frequency range of 24 to 42 GHz. The required LO power is 0 dBm between frequencies of 12 and 21 GHz. The RF receive port is WR-28 Uni-Guide™ waveguide with UG-599/U flange while the LO port is female 2.92 mm (K) connectors. Other port configurations are also available under different model numbers such as SSR-3331834012-KF-S1.
Suspended Substrate Stripline
Mini-Circuits’ model ZHSS-K21G+ is a suspended substrate stripline highpass filter with wide passband of 21 to 40 GHz. The typical insertion loss is only 1.0 dB across the passband, with typical passband VSWR of 2.0:1. The typical stopband rejection is 80 dB from DC to 13 GHz and 40 dB from 13 to 16 GHz. Ideal for rejecting unwanted lower frequency signals from mmWave communications systems and test and measurement applications, the 50 Ω highpass filter handles input power levels as high as 2 W at room temperature (+25°C).
