RFMW, Ltd. announces a web based tool that allows designers to create semi-custom Voltage Controlled Oscillators (VCOs) and Phase Locked Loop (PLL) synthesizers. Designers can search a large database of existing products based on parametric requirements and jump directly to existing product information.
RFMW, Ltd. announces design and sales support for TriQuint Semiconductor TGF2040, a discrete 400-Micron GaAs pHEMT FET. Designed using TriQuint’s proven 0.25 um pHEMT process, power and efficiency at high drain bias operating conditions are optimized. The TriQuint TGF2040 supports circuit designs to 20 GHz with up to 26 dBm P1dB, gain up to 13 dB and 55% power-added efficiency (PAE).
Vaunix Technology Corp. has announced additions to their LDA Digital Attenuators line. Five of their LDA digital attenuators are now available with N-type connectors. The LDA series of Lab Brick® Digital Attenuators includes 50 Ohm RF step attenuators with calibrated operation up to 6 GHz. These units connect to a USB port for control and power and require no additional DC supply voltage.
PMI Model No. PSD-6G16G-CD-1 is high power, switch box assembly that provides protection to front-end receivers when in the presence of high power signals. This is accomplished by sensing the input signal level and then switching the input signal into 50 ohms terminations when a set threshold level is exceeded. This assembly operates from 6.0 to 18.0 GHz and can handle input power levels up to 10 W CW.
PMI Model No. POB-16-48-22-LCA is a 4.0 to 8.0 GHz low noise amplifier which provides 16 dB of gain while maintaining a gain flatness of ±1.0 dB typically over the operating frequency. The noise figure is 3 dB typical and offers a typical OP1 dB of +22 dBm. The amplifier requires +12 to +15 VDC and the current draw is 225 mA typical.
PMI Model No. PS-360-3237-8-292FF is a high speed, millimeter wave, 8-bit digitally controlled, phase shifter that operates over the frequency range of 32.0 to 37.0 GHz. This phase shifter offers a low insertion loss of 13 dB typically and maintains a VSWR of 1.8:1. The total phase shift range is 358.593° having a step size of 1.406° and switches between states in less than 500 ns.
PMI Model No. PSD-2G6G-CD-1 is high power, switch box assembly that provides protection to front-end receivers when in the presence of high power signals. This is accomplished by sensing the input signal level and then switching the input signal into 50 ohms terminations when a set threshold level is exceeded. This assembly operates from 2.0 to 6.0 GHz and can handle input power levels up to 10 W CW.
PMI Model No. LM-18G40G-18-1W-292FF is an ultra-high speed, millimeter wave, high power RF limiter that operates over the frequency range of 18.0 to 40.0 GHz. This limiter can handle input power levels up to 1 W CW and provides a leakage output power of +18 dBm maximum and +12 dBm typical.
PMI Model No. P8T-2G6G-90-T-55-SFF is a high speed, single pole, eight throw, absorptive switch that operates over the frequency range of 2.0 to 6.0 GHz. This switch offers very-high isolation of 97 dB typical while maintaining a typical fast switching speed of 30 ns. The operating input power rating is +23 dBm CW with an insertion loss of 3.5 dB.
PMI Model No. PDVAN-8018-60-8-OPT25DBM is an 8-Bit digitally programmable attenuator that operates over the frequency range of 8.0 to 18.0 GHz. This model offers low loss of 3.6 dB typically and an attenuation range of 60 dB. This model was designed to handle input power levels up to +25 dBm CW under operating conditions and signal levels up to +30 dBm CW without damage.
