This is NOT a sales pitch. But, I've been reading an overtly sales-orientated trade mag that comes my way and found some interesting new gizmos that others might like to investigate. (1) HP has a line of PLL gear. A recent announcement is a 3V PLL synthesiser "to complete the four-chip IC set that provides all the active radio functions needed for several wireless applications in the 1.5-2.5GHz range." The HPLL-8001 is intended for use with an external VCO and the dual modulus prescaler contained as part of HPMX-5001 (a 1.5-2.5GHz up/down converter with a half-rate VCO with a 32/33 dual modulus prescaler, at +2dBm, down conv. gain 14dB, 10dB noise figure). Programming is over a 3 wire bus. Only 4mA op. current. Intended for DECT, WLAN and PCS applications... HPMX-5002 IF mod/demod includes VCO, prescalers, phase freq detector, downconverter to 2nd IF, limiting amp chain, data slicer and received signal strength indicator (RSSI) with >75dB range. HPMX-3003 LNA/switch/PA is a GaAs IC with LNA (2,2dB NF, 13dB gain @ 2GHz), T/R switch (55dBm 3rd order intercept point) and PA with +27.5dBm output with 23.5dB gain (at 3.6V). (2) Trimble's Lassen-SK8 module... embeddable board... which appears to be only about 5 times as long and and about 2 times as wide as an 'F' PCB edge connector. (3) The new power supply trick is 'ferroresonant' supplies, using a transformer that works in saturation with a capacitor-inductor (transformer) resonant circuit that is resistant to transients. _ .
