To meet the needs of the ZeenKo series of radio test instruments, we have produced a number of integrated circuits under the ZeeTK brand name. This ensures a continuous and reliable supply of our products. We also sell these chips to radio hobbyists and third party companies.
ZeeTK NE602A Double−Balanced Mixer
The NE602A is a low-power VHF monolithic double-balanced mixer with input amplifier, on-board oscillator, and voltage regulator in a SOP-8 package designed for use in high performance, low power communication systems. The gain, intercept performance, low-power and noise characteristics make the NE602A a superior choice for high-performance battery operated equipment.
This device pin2pin compatible NE602A/NE612A/SA602A/SA612A.
ZeeTK ZK10D LF-10.0GHz Broadband Low-Noise Amplifier
The ZK10D is a low noise amplifier (LNA) that operates in the LF to 10GHz frequency range. The device incorporates on-chip input/output matching circuits and is fabricated with GaAs pHEMT process. The device is provided in a 2x2 mm, 6 pin DFN package. This device provides 23.2dB power gain at 1.0GHz, 27.6dBm OIP3, and 17.4dBm OP1dB with single +5V supply. Can be used as a gain amplifier. The device’s minimum operating voltage can be as low as +3V, making it ideal for use as a first-stage LNA in low-power handheld devices.
