address/name. Do NOT reply on Newsgroups (I posted here, but will NOT read), and if I get much spam that address will be DISABLED, so you'd have to message via Ebay only. My Ebay feedback is 100% positive, not to mention 14 YEARS of Newsgroups trading without complains; also Ebay is better for your own security but if you've no Ebay account - email. Again, description is on Ebay but a few facts are copied here (for convenience):
TECHNICAL SPECS: A COMPLETE PDF is POSTED at
$50/unit - same new/sealed units but @33% cost- reason to sell is explained below. =95 wideband, 10MHz to 1.500 GHz =95 IP3 +31 dBm typ. =95 Low Noise 3 dB typ. (not bad for a MedPower amp, rather than dedicated LNA) =95 Gain, 40 dB typ., Flatness 1.2dB =95 VSWR IN 1.4, OUT 1.6 =95 P1dB Compression Point +15dB min, however charts indicate 17.6 to
18.7dBm =95 Connectors - SMA (50 Ohm impedance), gold-plated. =95 DCpower +12V nom @115mA max, but will take a range of 9-13V or wider. =95 More data, plots, etc. are in a datasheet (PDF) downloadable from manufacturer's website. Example of applications: communication systems e.g. cellular, satellite distribution, GSM/ISM; Radars, we're using them in a Middle- Stage Ampplifier block in an MRI (magentic) scientific instrument. MORE PHOTOS are at EXTERNAL SERVER as I CANNOT POST on EBAY for free beyond 1st free photo; at:------Reason to sell: Our RF Engineer has changed Product design in which this amplifier was previously used (a scientific instrument); so not all purchased lots of ZKL-1R5 could be finished before new design "kicked in". In the new design, ZKL-1R5 overloads the newly redesigned next amplifying stage (which became more sensitive) & we don't know a clean way to attenuate ZKL-1R5's gain (38-40dB!), lowering powersupply is not a solution & not enough. So instead we switched to using ZFL-500 amps with lower gain & narrower bandwidth (0.5Ghz, in fact all we need is
0.2GHz, not even 0.5GHz). As you imagine Minicircuit's policy is not to take them back, so forced to sell a 10-unit lot (but already stocked up on 60 ZFL-500's).I, in fact, come from a competing RF company (not to be mentioned) so not interested in promoting Minicircuits, but this is one of their better models; as far as I know it's using Gallium/Indium PHEMPTs or something to that effect and how they make it that cheap ($150 original, we ask $50) is a challenge.. It's a pity at the new company where I moved onto in 2008, which is USING RF Amps rather than designing them in the first place, we cannot use it due to excessive gain, also don't need $150+ highend amps anyway for our simple application under 200MHz. P.S. Again, more photos are at that
