2 Watt VHF linear amplifier
Once again my collection of projects creation has been interrupted by another necessity. Patrick and other people have asked me for a circuit of a VHF power amplifier. These circuits are my "standard" building blocks that can be used to...
UHF amplifier circuit
This UHF amplifier circuit project is beneficial for enhancing weak TV signals. The amplifier provides a gain of 10-15 dB within a frequency range of 400 to 850 MHz. To ensure optimal performance and reliability, the PCB tracks should be...
MICRF112 MICRF112: QwikRadio ?® UHF ASK/FSK Transmitter
The ADC12038 family consists of 12-bit plus sign sampling Analog-to-Digital Converters (ADCs) featuring serial input/output. These devices are equipped with configurable analog multiplexers that can accommodate 2, 4, or 8 input channels. Upon request, these ADCs can execute a self-calibration...
VHF UHF Low-Noise amplifiers using MAX2664 MAX2665
These devices feature a broadband low-noise amplifier (LNA) with an integrated bypass switch. The MAX2664 operates within the UHF frequency range of 470 MHz to 860 MHz, while the MAX2665 functions within the VHF frequency range of 75 MHz to...
1W UHF Linear Amplifier with BLW33
This circuit serves as an amplifier for small transmitters operating within the UHF band, specifically in the 450-800 MHz range. The amplifier operates in Class A, utilizing the well-known Philips BLW33 transistor. Although the construction is relatively simple, it requires...
Frequency Meter using PC
Here is a simple technique for measuring frequencies over quite a wide frequency range and with acceptable accuracy limits using a PC. It follows the basic technique of measuring low frequencies, i.e. at low frequency, period is measured for a...
MAX2664/MAX2665 VHF UHF Low Noise Amplifiers Circuit
This design circuit outlines a simple, low-cost, and ultra-compact VHF/UHF Low-Noise Amplifier (LNA) that can be implemented using the MAX2664 and MAX2665 devices, which are specifically tailored for VHF/UHF applications. The MAX2664 operates within the UHF frequency range of 470...
Frequency meter with 10Hz to 2MHz
The 7208 seven-metric system counter is utilized as a frequency meter. It features a latch and multiplexing function and incorporates a direct drive circuit along with a display driver circuit. The 7207 IC divides the output frequency of a 6.5536...
Grid DIP Meter
This circuit was developed by Luigi Falcone, I1FLC. It utilizes seven plug-in coils that cover a frequency range from 3.0 to 30 MHz within a Colpitts oscillator configuration. A coaxial socket, labeled J2, allows for the connection of a frequency...
